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.
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
