Reworking the text formatting code.
...
It's a mess of indirection and over-abstraction, and this commit
is the first step at cleaning that up. In addition to making the
code easier to follow, it's also notably faster.
The only downside is we've (temporarily) lost indentation
continuation on line wrapping. But that can be added back without
too much trouble later.

This makes international input popups get placed correctly for
terminals that do that.

Moved from termion to crossterm for terminal handling.
...
This should (hopefully) make led work on Windows now. Although
I don't have a Windows box to test on.
This also fixes a bug where control codes were ocassionally split
on input, resulting in e.g. a pg-down resulting in control
characters inserted into the buffer.

Using a smallstring implementation inside the screen buffer.

Made the screen buffer implemention way faster.
...
It's in a pretty good place now, I think. Although its memory
usage could be improved with a small string type.

Updating to use the new Ropey.
...
This is mainly just for kicks and giggles, since it really won't
work quite properly anyway, due to the lack of grapheme indexing.
The next real thing is to... well, start from scratch.

Fixed bug in buffer drawing code.
...
It was causing the entire last line to be re-scanned to find the
cursor drawing position if the cursor was at the end of the buffer.
This was both slow and resulted in an incorrect position, since
all the rest of the drawing assumes line blocks.

First attempt at making display code really take advantage of long line support.

It's not quite working right, but it does at least prevent performance
degradation.

WIP: handling extremely long lines with good performance.
...
The formatters now work on grapheme iterators instead of directly on
lines, which frees up the LineFormatter to break up long lines into
smaller blocks of text. This is partially taken advantage of right
now in various parts of the code, but more work is still needed to
get it both working properly and fast.
