at audio fixup. It did nothing of course lol
Reverted back to 16-bit pcm because it sounds marginally better than
8-bit

The audio output is still messed up, but this commit gets everything as
ready as it can get. Fixed up all the testbenches and added state
machines for everything

These were realy headaches but the testbenches are passing. We need to
take a look at the audio_buffer testbench for sure, it is way wrong and
needs reworked to use the interface. Should do a pass through every
module probably.

Initial work on rom_sd
...
This module needs way reworked to just be a state machine. I was trying
to get way too tricky with it so I went back to the drawing board and
made a state machine diagram for it. The diagram is included with this
commit. I also moved the current collection of documentation to a doc/
folder, and added a second-long audio rom to test everything out once
the rom_sd is working.

Fixed up debouncer and added some assertions
...
I moved around where packages are. I couldn't find any evidence of where
other people put them, but for now they are in the `lib/` folder. Other
infrastructure changes are that all the weird includes we need to make
the linter happy are gated behind ifdefs, so they don't mess with
vivado.
I kinda can't believe concurrent assertions work because there's so
little info about them, good to ssee they actually do something

This adds some unnecessary stuff into the debug core that I used to
troubleshoot. There are like 5 bugfixes here. Especially of note is the
low freq clock gen, I was trying to use modulo like you would do in a
computer program but it was too slow, so I had to move the logic around
a bunch.
