[Open Assets] SRB2 : Project Junio 2

After thinking about it a bit more, I'm going to restore the emblem progression with some small bonuses in a future update when I find the motivation to work on it again.

Changelog:
-> Remove emblem base progression
-> Remove Hub
-> removed SD version
-> Disable force character // vanilla characters lock
-> less enemy on Stormspire Heights , sunset grove and Vulcanic Rave
-> resize texture
-> added GS OptiMenu
-> sunset grove back into the level pack
-> application of ramp sector effect on every level
-> added SlainLBS music Wip_1

Hot fix missing texture

Sunset grove is no longer a requirement to progress . it may be replace in a another update

to-do list
-> revamp the hub
-> improve visibility and add indicators in the maps so that the player gets lost less
-> I would need help with the textures, some of them cause crashes.​
