Individual updates

Implemented some application-level UART code (reading, parsing, command-line, etc.)
Tested firewall integration
- It works as expected, but further synchronization is required for it to be actually usable
Assisted in preparing the vehicle for PittRace track testing
Tested telemetry reliability at PittRace
- Used the large 19 dBi dish antenna, mounted on a tripod
  - The range and field-of-view were quite sufficient for our test track setup
- UDP remains effective for our purposes
- Recorded CAN traces are generally consistent
  - Packets only dropped when the vehicle exited the track area

Schedule status

Firewall and UART integration continues; it remains feasible under our current schedule.
