Severons Customizable Endless

Adds a customizable endless mode to the end of the endless page that includes:

Included Regions

Laaaaa aaadd dddd ee rrrr

Excluded Sub Regions (All can be excluded but you might softlock yourself. I haven't tested all of the combinations.)

Micro management stuff like mass speed in each subregion, general mass scaling and rubberbanding, difficulty in each subregion, space compression, etcetera.

Win condition options

Starting artifacts (pick one, don't be greedy. Or not. Whatever you want.)

Starting items (Flashlight, Flaregun, Handgun)

Starting perks

Credit to the person who made Endless Service Shaft, I read their source code and it gave me my head start on making the button and game mode and such.

Planned additions once this is more than just a customizable endless mod:

Harder Mode

A few bindings and trinkets

Wizard Mode (heheheh)

My discord is severon_the_dragon, I'm pretty sure.
