Adopted your idea to just flip the high bit instead of
adding/subtracting. I still don't encode 255 by default because it makes
the file larger, but added an option that adds 255 to the unsafe list.
Added an option to generate a "poor man's trigger file" instead of
either call or savem.

It's not 100% complete yet, but I made a two-stage BASIC loader
<https://github.com/hackerb9/co2do/blob/main/co2do> that includes a
little 8085 routine <https://github.com/hackerb9/co2do/blob/main/
decode.asm> for speed. You just run ./co2do FOO.CO <http://FOO.CO> and
it'll create a FOO.DO that can load speedily.
