Gap checklist crash

[DCxDemo]

Cannot access gap checklist menu. Figure out the requirements and reformat gap arrays to fix the issue.

• thps1
• thps3
• thps4

3 and 4 basically inherit th2 checklist system, hence easy to fix.
th1 on the other hand was before that, its tags are not lined up in regions.
mhpb wont work at all due to different gaps format (names stored in trg)
