v0.2.1

TreeAMR v0.2.1

Diff since v0.2.0

TreeGRRMHD's mesh requests (#20). Additions only; existing code is unaffected.

• A state vector over several field sets: statelength, statevector, statearray, scatter! and gather! take a tuple of field sets; staterange and stateview are new exports; volume_weighted_norm(sets, u).
• map_blocks!(…; workgroupsize) passes a workgroup size to a device launch (ignored on the CPU).
• Per-set boundary hooks in regrid!, fs => (schedule, hook).
• adapt_to_initial_data! over several field sets at once.
• Outflow faces, Forest(…; outflow = ((lo, hi), …)): zero-gradient ghosts filled by the schedule on every backend and across ranks, without a hook.
• Bounded conservative prolongation, Operators(…; family = Conservative, prolongation = 3, bounded = true): the ghost fill and the regrid create no new extrema, and the transfer stays conservative and exact for linear data. Also accepted at prolongation = 1, which is bounded already.

The forest's face kinds moved into one field, which changes the companion interface: TreeIOHDF5 needs a release that accepts this version.
