Reorganize and format the spade codebase

[grymmy]

I apologize for the monster PR - it does the following:

• Reformats all code to be tab delimited (didn't choose this out of some sort of religious belief, used the default C/C++ autoformatting in VSCode)
• Separates concerns by breaking out many of the logical components into separate compiled sourcefiles - audio goes in audio, button handling in buttons - cuts rpi's main.c by 100+ lines
• Separates out a main constants header file to put important, high-level configurations and macros
• Modifies some of the CMake configs to fix compilation issues resulting from these changes

A member of the Team first needs to authorize it.

I am going to abandon this and probably re-attack this anew.
