unvis: implement meta and ctrl characters ('\M__' and '\^_')
While these characters are really weird to handle, here is a fairly
simple implementation that need some more testing (and a proper
secondary source to compare against).

unvis: implement proper '\xff' and '\377' escape handling
In particular, previously such escape handling would break because we
would attempt to encode characters >0x7f as runes -- which would then
result in escapes that want to encode multi-byte characters breaking.

There's still some work necessary in Vis() to make it act sanely when it
comes to arbitrary bit streams. Not to mention that we need to figure
out what we actually want to do there...

unvis: implement partial unvis(3) implementation
Also add some unit tests -- one of which currently fails due to ongoing
design discussion about how certain escape codes should be handled.
