Required to add some basic hacks to expose a regionstats object
in the TickRegions data class, but this ensures that the retrieval
is thread-safe and could possibly support other data exposure
for async reads.
Additionally, since DecimalFormat is not thread-safe we need
to use ThreadLocals to instantiate them. Change the format
as well to use commas to separate groups of digits when
formatting large numbers so they are easier to read.
For example, 1000 becomes 1,000.
The code to stop all brain tasks is required to pass the current
game time to the tasks it stops. But, when a villager is being
portalled, the copied entity does not have any running tasks. So,
we can simply return early before invoking getGameTime if there
are no running tasks.

Everyone had access to /tps for the private tests, but we cannot
trust everyone to use it responsibly for the public test
(i.e revealing coordinates of all logged in players).
