I am definitely struggling a bit with what's coming back from the USB calls, and I don't know yet how really to initialize the neopixel There's a bunch of commented out code that is in the direction of what I mean to do.

WIP: trying to have the morse code generation at least emit .__. to the serial port, but reinitializing the interface doesn't make sense. Need to refactor so that the global abstraction for the hardware we've configured is more globally accessible (or easier to pass around.)

It still would benefit from a letter queue, but this works as long as you don't type too fast. Needs some cleanup though.

I left the stubs of the character queue in place, so I can finish that out, but this is way shorter now. I wish I had a way to generate the initial queue state, but iterators are part of std, which we don't have access to.

Tried to make the USB loop provide queue length stats, but not having std in embedded rust meant I wasn't sure how to convert my usize into a string. (I made it a u32 at least.)

QA'd all letters and numbers but haven't verified punctuation.

we do handle an empty queue. Next, make the queue into a circular buffer, and push stuff into it. It would sure be nice to have some tests.

Clean up some cruft. Conform to more rust standard naming.
