Updated MIT License file to reflect new online handle

• Fix Corpse I being detected as the floor to extend the total length by 1 instead of Corpse II. This was only noticeable if you had a mod that continued runs past Mother outside of Greed Mode and specifically went to the Blue Womb, meaning this mod should now be compatible with said mods.

• Added icon for Tainted The Soul, registered as a twin to Tainted Forgotten.
  
• Added support and toggle for Co-op Babies/Found Soul
  
• Added support and toggle for Co-op Ghosts.
  
• Added API functions BlacklistPlayerType, SetBabyIcon and ResetBabyIcon.
  
• Added API callback PRE_ICONS_INIT.

• Fixed twin players potentially being grouped with the wrong character when over 4 players.

• Added ImGui support. The mod has a new menu for mod settings, in which you can toggle a variety of options.
  
• Co-op players can now be rendered alongside you on the progress bar map. Up to 4 players can be rendered, but more can be displayed if there are any twin players (Esau, Tainted Lazarus with Birthright, etc). Can be toggled, enabled by default.
  
• Added three custom callbacks. Handy for managing the icons during creation/render and a lot of information on them.
  
• Added Dark Esau to render on the previous floor. Can be toggled, enabled by default.
  
• Added transparent icons for LazB/LazB Risen for Birthright. Can be toggled, enabled by default.
  
• Strawman-like players are also allowed to be treated as a co-op player, being rendered on the map. Can be toggled, disabled by default.

Added StageAPI support! The code bases itself around the default transition render so it may have incompatibility for any that use a custom one. Please report any issues you find in the workshop's comments!

• Added additional safety checks to revert a modded coop icon to the default Isaac icon if the sprite ever fails to play properly.
  
• When loaed modded coop icons, it now checks for the first valid frame in it's animation if the one in layer 0 is not present. This was primarily done for Epiphany support, as their icons were on a different layer. If this causes icons to load something nonsenical in the anm2 that isn't a co-op icon, I only have the mod developer to blame at that point.

• Added UniqueProgressBarIcon.StopPlayerTypeRender()

• Added an icon for Lazarus Risen (non-Tainted)
  
• Updated skin color of Tainted Lazarus Risen's icon a bit

• Removed unnecessary coop menu graphic replacement
  
• Removed the random 1-pixel offset for moving forwards (that was placed by me by eyeballing it, it should be fine without it)
  
• Added a unique icon for Tainted Lazarus Risen as he did not have his own coop icon
  
• Fixed Corpse I and Corpse II offsetting the icon by half a map icon

• Fixed not accounting for Blue Womb's extension of the map length
