Just for consistency, update version in Cargo.toml

Fix SAN promotion notation

It wasn't showing the check or mate signs and there were issues
with the move disambiguation.
I hope everything is fine now, the code is most probably over

to rewrite it.

Update Readme with the new features and a new gif

Increase a bit the time we may wait for the engine

Github Actions: Fix the Windows-32bit target path

Merge branch 'main' into font-pieces-with-tabs

Update demo gif

Small usability improvements.

screens.
Both rating sliders were starting at 50, now they have sane
initial values (min 0 - max 1000)
