14th update to Heraldry Studio

How is everybody?
A rather technical update this time. Until now Heraldry Studio has worked single-threaded, like programs of ancient computing times. I tried to include some multi-threading for resource loading and similar things. I have to confess, computers won this time, and HS still isn't multi-threaded program. Nevertheless some speed improvements were achieved anyway - now larger resource file size will not impact speed.

Two partition styles - "Arched" and "Rayonny" - are added to the list. They were secretly in anyway and would appear in random coats of arms, so, after a vote in Discord, I added them to be picked deliberately. They might look buggy in some configurations.

Vote is on again: it's time to pick the next batch of charges to add!
