Add fake GPS messages to parsley source, remove old messages

[EmpiricalCode]

Description

Removed the old fake messages under FakeSerialCommunicator as well as the code populating those fake messages, as the messages are outdated.

Updated FakeSerialCommunicator.__init__ and FakeSerialCommunicator.read to generate new fake messages (currently only related to GPS). These messages are based on an omnibus log saved from a previous competition and the RocketCAN packet docs.

Note: parsley repo must be updated to support new format of messages. Will create a PR for this.

This PR closes #315.

Developer Testing

Here's what I did to test my changes:

• Ran the parsley source with the --fake flag through omnibus bus into the printer sink to make sure the messages were being encoded properly.
• Artificially set the timestamp to 16,777,000 and made sure the it was reset back to 0 once it exceeded 16,777,215.
• Manually took DDM coordinates of generated messages and made sure they were within the Waterloo region.

Reviewer Testing

Here's what you should do to quickly validate my changes:

• Take some generated coordinates and check they are in the Waterloo region.
• Make sure generated values are accurate to what is expected from real-world data (num_sats, quality, etc).
