Cleaned up git repo. Added FSBL projects, IMU logger project, deleted comm_dev. Put bootimage and Debug directories in .gitignore

Realized that uart_sendBytes won't work, because checksum isn't calcualted. Reverted to sending single bytes

Fixed issue with UART timeout interrupt not firing. Added BENCH_TEST mode for testing communication.

Integrated changes from comm_dev (interrupt-driven UART) and updated code to work well with the new style. Compiles, but have not tested running yet.

Weekly reports should show from Google Drive now, so we don't have to manually upload them. But, deploy script is broken because lftp is no longer available?

Changed interrupts to call own handler. Seems to get called, but not modifying secondaryEnd variable

Implemented copying of UART received data to circular buffer and processing circular buffer. Has not been tested

Autonomous mode is throttle-only. Fixed bug in stringBuilder that would fail to resize byte data. Packets that don't have a matching checksum are thrown away now.
