Bonus Maps are going to have
their own dedicated level selection map
because they play in no specific order.
I will make the dedicated Bonus Hub
"MAPB0."

NOTE: "Grunty Industries by ChargingTurnip" 
makes extensive use of custom exits. 
Do not change their extended mapnums
unless you want to deal with that shit
lmfao.

NOTE: "MAPFU.wad" is a deceptive
filename it has custom assets.
If I remember correctly they're
merged into the pack already,
but it would still be good to
cross check, and remove them from
the file itself.


Every stage except for Grunty Industries 
should use the "MAPB1-5 mapnum." 
No specific order required.
