Doom SNES Improvement Patch

This patch provides improvements for SNES Doom.

This is basically my MSU-1 patch without the MSU-1 music. The mouse fixes from this patch have been added to that one as well as of version 1.4.

Changes:
Any episode can now be started on any difficulty, as in the Japanese release.
Adds circlestrafing, modified from a patch by xttl from https://www.romhacking.net/hacks/5272/
Fixes the Hyperkin Hyper Click mouse not working, and fixes being unable to exit intermission screens with the mouse.
Insert mouse into controller port 1.

Version 1.1 (hotfix) fixes the speed of the original SNES mouse not matching the vanilla game. This has been fixed, and now both mice work perfectly

Version 1.2 (09/18/2024) makes the publisher logo screen skippable.

Version 1.2.1 (hotfix) fixes mouse input not speeding up text on text screens.

Mouse controls:
Drag forward/backward: move forward/backward
Drag left/right: turn left/right
Left click: fire, select options
Right click: use
Right click + drag backward: cycle weapons
Left+right click: pause
