FTB Chunks is the only mod in the FTB suite that nothing else depends on --
FTB Quests requires FTB Library and FTB Teams only, and ships no claim-chunk
task type -- so it can leave without touching quests. Open Parties and Claims
takes over claims and force-loading, and the Xaero's suite restores the
minimap, world map and waypoints that b0542f9 removed.
The three Xaero's entries are byte-identical to the ones b0542f9 deleted, so
this reverts the map half of that commit rather than integrating anything new.
Xaero's + OPAC is also the pairing both projects document: the world map
displays OPAC claims and lets you claim and forceload from the map screen.
Drops config/ftbchunks-client.snbt and the .packwizignore negation that
shipped it, since the FTB Chunks minimap it enabled no longer exists. Also
keeps authoring/review material and migration scratch out of the pack index.
Server-side follow-up (not shippable, lives in the world save): set
maxPlayerClaimForceloads to 25, point primaryPartySystem at FTB Teams, and
decide claims.forceload.offlineForceload.
