Add USB drive to roboRIO for swap memory

[jkleiber]

Purpose On October 7th 2024, we observed that the roboRIO ran out of RAM with only the drive and intake subsystems enabled. This is a roboRIO 1, so it has limited RAM.

The objective of this ticket is to install and configure a USB drive to be used as swap memory on the RIO. This should sufficiently mitigate our memory issues for offseason competitions

Project Scope

• [x] Add USB drive to roboRIO
• [ ] Configure drive to be used as swap memory

I did not do swap space but installed a USB drive for logs to save to. I did disable the web server and swap lvrt to the shell script. We're no longer getting code crashes, free disk is around 55 MB, free ram around 77 MB.

We can add on the swap space stuff if needed later.

77MB is a good amount of RAM, I hope we can avoid using all of it

I'm going to close this for now since we didn't see issues on Wednesday. If we run into problems again we can reopen this or create a new issue
