Wez Furlong 86c1d50b4a WIP: improve CSI parsing fidelity 
The original design of the vtparse crate was inspired by the vte
crate.  There were some assumptions about the shape of CSI sequences
that were lossy and that is posing a problem when it comes to
implementing DECRQM.

This commit improves the situation by adjusting CsiParam to be capable
of capturing all of the possible parameters as well as intermediates.

This commit isn't done; I just need to push it to transfer it to another
machine.

vtparse

This is an implementation of a parser for escape and control sequences. It is based on the DEC ANSI Parser.

It has been modified slightly to support UTF-8 sequences.

vtparse is the lowest level parser; it categorizes the basic types of sequences but does not ascribe any semantic meaning to them.

You may wish to look at termwiz::escape::parser::Parser in the termwiz crate if you're looking for semantic parsing.

Comparison with the vte crate

vtparse has support for dynamically sized OSC buffers, which makes it suitable for processing large escape sequences, such as those used by the iTerm2 image protocol.
