Incorporate Pan-African-Latin shaperglot profiles directly into shaperglot

[NeilSureshPatel]

@simon, per our discussion today, here is a link to sg-bulk-builder.py which I am using to create shaperglot profiles. Currently, it only builds the no_orphaned_marks test. There is some setup for the forthcoming unencoded glyph variant test. I also was planning a smcp test for orthographies, but that seems like an easy thing to roll into default orthographies test with a conditional feature switch for smcp.

I've added this to the repo, and changed its directory so that it writes to shaperglot/languages directly. I've also committed its output to the repo.

Thanks, Simon. Everything seems to working well!
