Moved from decimal to double, optimized code

[Prevter]

This is probably the last performance update. Everything that i could've optimized is now optimized
This version also includes compiled binary for .NET 7 rc1 to test it before fully moving

Main changes

• Changed from decimal (128 bit) to double (64 bit). This made calculations faster, while not changing the precision
• Made all classes sealed. This makes classes without inheritance and improves performance
• Rewrote combinations founder algorithm and embeded it in main loop
• Fixed minor bug in Discord RPC
• Fixed link to the themes list in settings

Other

• Bump HtmlAgilityPack from 1.11.43 to 1.11.46

Full Changelog: v.1.2.0...v.1.3.0
