Implement and test Sound and Music structs and DAC output (sound effects can wait for later)

Note: some registers are locked by default and need writes to their GPIOCR and GPIOLOCK bits (e.g. PD7). View diskio.c and signal tables on pg 1329 of manual.

Note: any new files added to the Keil folder also need to be added within Keil so that it compiles. Right click the "source" folder on the left and hit "add existing files to group"

Note: both diskio.c and TExaS.cpp use Timer5A. Change the diskio.c timer to timer 1 or smth

Note: sometimes when the SDC doesn't like you, the initialization function returns a F_NOT_READY or an F_NO_FILESYSTEM error. This is a bug that I think might have something to do with waiting for messages or even screwing up the formatting of the SD when initializing. Also it usually happens after an initially successful test so maybe it has something to do with that. Regardless, a temporary way I've found to fix it is to just run until the while true loop, stop the program, remove the SD, and reformat it with FAT16.

It's freezing at the writedata function in ST7735.c when waiting for the receive queue to be not empty
