Update Paper and add configurable region shift

The region shift is configurable under `grid-exponent`, which
allows setting the region shift to any value in [0, 31]. Note
that values above 6 affect the lock shift, as the lock shift
currently is computed as max(ticket shift = 6, region shift).
The shift is left configurable for now as the lower default
shift of 2 may have negative performance impacts.

The default region shift has been adjusted to 2 from 4, and
the empty chunk buffer has been reduced to 8 from 16. These
changes reduce, but do not eliminate, player spread
requirements. The previous block range was around ~1500 blocks
at VD = 10, but is now closer to ~900 blocks at VD = 10. This
roughly reduces the area that each player uses in the regioniser
by 2.5x.
