[Open Assets] no respawning during multiplayer bosses 2.1

this mod will prevent respawning during bosses in multiplayer by setting coopstarposts to teamwork in boss levels, and then reverting that change in non-boss levels
to change what coopstarposts should be set to in non-boss levels, use the console variable nonbosscoopstarposts
if you need to disable the mod mid-game, set allowrespawningduringbosses to yes
this is my first mod, so if you have any suggestions to improve it, please tell me
