Patch mixed pools grotto and dungeon ER blue warps

[mracsys]

Blue warp entrance indices are hardcoded in both cutscene commands and the blue warp actor. With non-mixed ER this is handled by modifying the entrance table. With mixed entrance pools, grotto exits are not in the entrance table and cannot be referenced with this method. This PR modifies all hardcoded blue warp entrance indices for blue warps that should lead to grottos. "Normal" entrance indices still use the entrance table as before.

Notes for the cutscene traces to identify the addresses to override are included in the Notes folder.

Thank you for the PR, it will be good to have this finally fixed 😅

The changes make sense to me but I feel like the fix should also apply to grotto entrances (ie. indexes above 0x1000). It only matters for decoupled+mixed pools, but in theory a dungeon exit could lead inside a grotto, in which case the entrance table override wouldn't work either if I'm not mistaken

I had hoped it would be as simple as changing the index check to 0x1000, but blue warps to reverse dungeon entrances are going to the warp pad instead of the dungeon exit, affecting the Requiem check and Forest Temple entrance. I'll keep digging.

Related, there is a regression from the mxied pools multiselect that excludes reverse entrance pools from the mixed pool in decoupled. I found it when my plando for dungeon exits to grottos testing failed. I'll make a separate PR with a fix for that.

I was overthinking it. Dungeon ER reverse entrances already swap blue warps with blue warps, that's nothing new.
