Kartik Agaram dbd7082a0e 7489 - include GNU Unifont
https://en.wikipedia.org/wiki/GNU_Unifont#The_.hex_font_format
http://unifoundry.com/unifont/index.html

Since GNU Unifont is covered under the GPL v2, so I believe is this repo.

Kartik Agaram be87d72335 7486 - primitive for reading keys
It also clears keys after reading them, allowing us to read more than 16
keys.

Kartik Agaram 3f7db804c9 7480 - baremetal/ex3.hex now draws multiple pixels
I was wrong in commit 7437 that only one keystroke was working. The problem
was just that I was getting _too_ many events. I wasn't handling key-up
events, and they were entering the buffer, and I was not skipping null
events since the circular buffer is currently considered to be null-terminated.

ex3 isn't done yet; it can only handle 16 events. Apps need to be clearing
the keyboard buffer.

The ol' 8-byte-register-names issue strikes again. There's no way to access
the lower 8 bits of ESI.

There's still a bug in baremetal/ex2.mu; it's printing transposed somehow.

Kartik Agaram 0daf12c59a 7469 - first working baremetal Mu program
It doesn't _quite_ do what it should, so this is more precisely the first
_buggy_ baremetal Mu program. But the tooling works, at least.
