## Summary
This pull request introduces significant enhancements to the AirSpace class within our network simulation software, aimed at improving the realism, configurability, and accuracy of wireless network simulations. These changes include the addition of new enums and attributes, enhancements to the configuration schema, and improvements in bandwidth management and transmission logic.
**Additions**
- **Enums and Attributes:**
- **AirSpaceEnvironmentType Enum**: Defines various environmental settings that affect wireless signal propagation and interference.
- **ChannelWidth Enum**: Specifies available channel width options for wireless interfaces.
- **Channel Width Attribute**: Added to WirelessNetworkInterface for dynamic adjustments based on the operational environment.
- **airspace_key Attribute**: A tuple identifying the frequency and channel width combination for bandwidth management.
- **airspace_environment_type Attribute**: Sets the overall environmental context of the airspace, influencing all contained devices.
- **Functional Enhancements:**
- **SNR and Capacity Calculation Functions**: New functions estimate_snr and calculate_total_channel_capacity have been implemented to compute signal-to-noise ratios and channel capacities dynamically.
- **show_bandwidth_load Function**: Provides a visual representation of the current bandwidth load across different channels.
- **Dynamic Speed Setting**: The speed attribute of WirelessInterface is now adjusted dynamically based on frequency, channel width, and environment.
- **Configuration and Testing:**
- **Configuration Schema Update**: The simulation.network config file schema now supports setting the airspace_environment_type.
**Changes**
- **Interface and Performance Adjustments:**
- **NetworkInterface Speed Type**: Changed from int to float for more precise speed definitions.
- **Transmission Feasibility Check**: Updated the _can_transmit function in Link to better handle current load and bandwidth capacities.
- **WirelessRouter Configurations**: The configure_wireless_access_point function now takes channel_width as an additional parameter.
- **Grouping Adjustments**: WirelessNetworkInterfaces are now categorized by both AirSpaceFrequency and ChannelWidth.
- **Transmission Logic Overhaul:**
- **Interface Adjustments**: Modifying an interface's settings now necessitates its temporary removal from the airspace, followed by a recalculation of its data rate and reintegration under new settings.
- **Blocking Overloads**: Strengthened the logic in AirSpace to prevent transmissions that would surpass the available capacity.
**Fixes**
- **Transmission Permission Logic**: Fixed the can_transmit_frame function to accurately enforce transmission limits based on current network load and available bandwidth.
**Conclusion**
These updates significantly enhance the fidelity and flexibility of our network simulation tool, enabling more accurate m...
This commit introduces several key enhancements to the AirSpace class, improving the realism and configurability of the wireless network. Major additions include the AirSpaceEnvironmentType and ChannelWidth enums, dynamic adjustment of interface speeds based on environmental settings, and comprehensive bandwidth management features. Additionally, the software now supports configuration of channel widths via the config file, incorporates accurate SNR and capacity calculations, and enforces bandwidth limits more effectively across wireless interfaces. Updated tests ensure that the new functionalities integrate seamlessly with existing systems.

## Summary
This PR removes the hardcoding of Link bandwidth, and makes it possible to be configured via the network yaml definitions.
Link bandwidth will still default to 100 if this is not present, to prevent breaking all previous defined networks.
## Test process
All tests continue to pass.
`basic_network_config.yaml` now provides a non-default link bandwidth which is confirmed within unit tests.

## Summary
Some minor changes to the network_simulator_demo jupyter notebook so that all cells run.
I've updated the notebook to use a **very lightly** modified version of the ARCD UC2 network that it has been using.
_I've added a single route into the router_1 route table so that `network.get_node_by_hostname("router_1").route_table.show()` returns something visible. I didn't want to have this within the 'normal' uc2 network. Don't @ me._
Corrected a path typo in `basic_lan_network_example()` so it correctly loads that network config.
## Test process
I've not broken any existing tests, and the notebook now runs with fully populated cells.

## Summary
Built three networks, one is the minimal network, one is a basic LAN, and another is a nice beefy multi-LAN setup with ISP and DNS along with applications, services. Documented the process when building the config files. Included the config files as example configs for use.
## Test process
Tested the shit out of the big multi-lan network.

## Summary
Refactor of `DatabaseClient` and `DatabaseService` to update how connection IDs are generated. These are now provided by DatabaseService when establishing a connection.
Creation of `DatabaseClientConnection` class. This is used by `DatabaseClient` to hold a dictionary of active db connections.
## Test process
Tests have been updated to reflect the changes and all pass
