[Toybox] uuen/decode

[Erich Plondke]

Looks like I might be a bit late on this browsing the archives... but
uuencode and uudecode implementations are attached.


Both passed basic tests.  Support both base64 and traditional format.

Also, I needed to put parens around min/max, but I think a better
option was presented that didn't have the duplication problem for
operands with side effects (like x++)
