Updates and fixes
pacman-mirrors was rebuilt to match the Python 3.9 release/update.
With that rebuild several changes - not previously released - has been made.
The most prominent is probably the ability to supply countries to use by using - almost - any mix of upper/lower case characters and the possibility to use the country code instead of the full country name.
pacman-mirrors still requires you to spell the countries or country codes right but as everything is compared using lower case and country code - you can do - almost - as you like.
If you use duplicates in the country argument - they will be removed.
The experimental async argument is dead - it was no good anyway.
Some fixes and changes has been related to the ARM architecture.
