Fix soft hyphens not being preserved when round tripping text through the terminal
...
Also roundtrip all characters in the Cf category.
Characters with the DI (Default Ignorable) property are now
preserved but not rendered and treated as zero-width
as per the unicode standard.

Round-trip the zwj unicode character
...
Rendering of sequences containing zwj is still not implemented, since it
can cause the collapse of an unbounded number of characters into a
single cell. However, kitty at least preserves the zwj by storing it as
a combining character.

Get rid of the option to use the system wcwidth

The system wcwidth() is often wrong. Not to mention that if you SSH into
a different machine, then you have a potentially different wcwidth. The
only sane way to deal with this is to use the unicode standard.
