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

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.
