2) Shows events asynchronously.
3) Shows server status in the bottom status bar.
4) Automatic retries on disconnects and error conditions.
Also added type annotations and necessary pylint/mypy configuration
Add an entry point for aqmp-tui. This will allow it to be run from

The 1.0.0 version of Zbb does not contain gorc/gorci. Instead, a
orc.b instruction (equivalent to the orc.b pseudo-instruction built on
gorci from pre-0.93 draft-B) is available, mainly targeting
string-processing workloads.
This commit adds the new orc.b instruction and removed gorc/gorci.

This reassigns the instructions that are part of Zbb into it, with the
notable exceptions of the instructions (rev8, zext.w and orc.b) that
changed due to gorci, grevi and pack not being part of Zb[abcs].
