Replace go-libvterm package with tcell-term. go-libvterm provides the
embedded terminal for aerc. It uses a statically linked C library,
requiring CGO.
tcell-term is written in pure go and is written to be portable with
tcell applications by implementing the tcell Widget interface. This
allows the terminal to take a view (which aerc already supplies) and
draw directly to it, as well as issue tcell Events to a Watcher.
Enable setting cursor shapes in embedded terminals.
