## Summary
Carried over hit fixes from internal that backtracked on the complex channel width stuff for now and focussed on getting a stable data rate baked in for each frequency. Implemented overriding of frequency max capacities on the airspace. updated documentation to reflect the changes in airspace.py.
## Test process
- Original tests still work
- Tested reading the frequency capacity overrides from config file
- Tested that setting the frequency override to 0.0 blocks the channel
