Aaron Kimbrell 17425c1e44 fix(zone): read a zone's paths as the chunk the client reads ...

The client reads a zone file's paths as a chunk of its own
(LuzFile::ReadLUZFile copies the u32-sized chunk, ReadLUZPaths reads
it, 1.10.64) and drops every path when it refuses any of it:
- a chunk version of 2 or more, or 10000 paths or more (ReadLUZPaths);
- a path of version 19 or more, 10000 waypoints or more, or a
  waypoint with more than 99 name/value pairs (LevelPath::FromBuffer).

The reader read the paths straight from the file, trusting the chunk to
be well formed. It now reads the chunk by its size, reads the paths
from it with the client's limits, and when one is refused the zone has
no paths (logged), while the rest of the zone file still reads.

Every zone file on disk reads the same paths as before.

The unit tests' sample zones now give the path chunk its real length.

Check in game: moving platforms, NPC patrols and spawners work as
before on every world.
