Add ability to write anvil chunks (#516)

# Objective

- Follow on from #510 by adding the ability to write and delete chunks
in anvil files.

# Solution

- Users can change the compression method and whether to write oversized
chunks, in case they want to write anvil files compatible with older
versions of Minecraft.
- `LruCache::try_get_or_insert_mut` is something I have [pull
requested](jeromefroe/lru-rs#178) to `lru`, we
can switch to that once it's merged.
