- Enhance NicObservation for detailed NMNE event monitoring.
- Add nmne_config options to simulation settings for customizable NMNE capturing.
- Update documentation and tests for new NMNE features and simulation config.
## Summary
- Made the data manipulation red agent be able to choose between the two clients to start operating on
- changed the attacker name in the config to 'data_manipulation_attacker' to because it is no longer tied to any client
- Updated the documentation notebook accordingly.
- Fixed a bug where the database client made a new connection every time it sent a SQL query (it tries to reuse its most recent one instead)
- Fixed a bug where link loads were not being cleared between episodes (?)
**warning** - the green agents are not working properly after reset right now, but I'm gonna fix this in the next ticket where I refactor episode reset.
## Test process
- unit tests pass
- UC2 notebook passes with both clients. (currently this doesn't work after an episode reset, but the very next thing I'm gonna work on is refactoring the reset, so I don't want to waste time fixing this.)

## Description:
This pull request introduces the Firewall class and extends the ACLRule functionality within PrimAITE to provide comprehensive network traffic management and security capabilities. These enhancements enable detailed control over data flow through network simulations, mimicking real-world firewall operations and ACL configurations. The updates focus on the addition of a Firewall node that extends the Router class functionalities and the enhancement of ACLRule to support IP ranges through wildcard masking, thus offering granular traffic filtering based on IP addresses, protocols, ports, and more.
## Key Features:
**Firewall Class:** A new class that extends the Router class, incorporating firewall-specific logic for inspecting, directing, and filtering traffic between the internal, external, and DMZ (De-Militarized Zone) network interfaces. The Firewall class supports configuring network interfaces and applying Access Control Lists (ACLs) for inbound and outbound traffic control.
**Enhanced ACLRule:** The ACLRule class has been updated to support IP ranges using wildcard masking. This allows for more flexible rule definitions, enabling users to specify broad network ranges or individual IP addresses in ACL rules.
**Comprehensive ACL Configuration:** Six distinct ACLs (internal inbound, internal outbound, DMZ inbound, DMZ outbound, external inbound, and external outbound) provide meticulous control over traffic flow, ensuring robust network security. Examples included in the documentation illustrate how to configure ACLs for common scenarios, such as blocking external threats, permitting specific services, and restricting access to sensitive internal resources.
**Intuitive Interface and ACL Management:** Simplified methods for configuring firewall interfaces and ACL rules enhance usability. The Firewall class offers intuitive functions for rule management, including adding, removing, and listing ACL rules.
**Detailed Documentation and Examples:** Accompanying the code updates, comprehensive documentation and example configurations are provided, detailing the use and configuration of the Firewall node and ACL rules within PrimAITE simulations.
## Impact:
The introduction of the Firewall class and the enhancement of ACLRule significantly broaden PrimAITE's capabilities for simulating realistic network security scenarios. Users can now accurately model the behavior of firewalls in their network simulations, applying complex ACLs to control traffic flow and enforce security policies. This update enables more detailed network security analyses, teaching, and experimentation within the PrimAITE environment.
## Test process
Extensive unit tests have been added to cover the new functionality, ensuring reliability and correctness. Tests include scenarios for firewall configuration, ACL rule application, traffic filtering based on various criteria, and interaction between different network zones.
