* Modifies custom sequence loading to bypass other sounds being loaded in AudioCollection to fix missing custom sequences on load.
* Modified `audio_load`'s sequenceMap allocation to utilize `AudioCollection`'s sequenceMap size to account for all audio assets already loaded into that sequenceMap. This gives a non-arbitrary number in addition to the vanilla sequence count to allocate with for `audio_load`'s sequenceMap.
Added `HasSequenceNum` to `AudioCollection` as well to streamline the check against `AudioCollection`'s sequenceMap to skip the non-sequence assets in there.
Added clarification comment for seqNum and MAX_AUTHENTIC_SEQID section.
* Clarified comment about AudioCollection seqNum and MAX_AUTHENTIC_SEQID.
* A bit more on comment from the last commit.
* Rename "SFX Editor" to "Audio Editor"
* Move some functionality out into a new class `AudioCollection`
* Add a tab to exclude sfx/sequences from shuffle pool
