v1.2.1 - Small seed change & new export

The only game change in this update is to seeding - it is now guaranteed that you will get 4 memory rules. Previously you could technically get 3 or 4, but it was much more likely to be 4, and will keep getting likelier the more rules I add. In retrospect it’s a bit silly for it to work that way, so it’s changed now.

This is actually mainly an experiment with the “new” single-threading web export in Godot 4.3. I only noticed one issue - for some reason the generate seed sequence wasn’t getting random pitches. For now I really don’t know why that is, so I just made the sound less annoying for the web version.
