tests: remove instr blacklist
...
Because scas isn't used as a reference anymore, no need to blacklist its bugs
anymore.

zasm: add poor man's indexing in instr table
...
There's a lot of looping through that table. At first, I wanted to add some
bisecting, but 16-bit additions and multiplications involved made the idea a
bit less appealing. I went with a very basic, hardcoded index which should
speed things quite a bit at a minimal complexity cost.

There's a couple of bit fiddling instructions that didn't have their

would have required a special routine. Not anymore.

recipes/ti84: first step

This was mostly lifted from my "tihello" example, but it required significant
adjustments.
This commit also introduces a font management system. A lot of fonts are
available online, but sources aren't always clear so to avoid copyright
landmines, I re-created my first 5x7 font from scratch.
As it is now, this resulting ROM gets "Collapse OS>" to be displayed on the
LCD screen. Much work still left to do.

stdio: remove a layer of indirection in GetC/PutC
...
We use zasm's ability to use labels in .equ directive.
We didn't do it before because for a while, we were in between scas
and zasm (scas was used in automated tests) so we needed to use the
lowest common denominator: zasm doesn't have macros and scas can't
use labels in .equ directives.
This forced us to add this layer of indirection. But now that we are
completely cut from scas' dependency, we can use this nice zasm's
ability.
