Description
When using the mini-block encoding we can checksum each mini-block with a CRC32. Blocks should only be 4-8KiB and so CRC32 should provide pretty strong protection.
When using the full-zip encoding we will actually need to checksum each individual value. Since we don't use it until we hit 128 bytes then adding 4 bytes is probably not too detrimental.

Research direction
The issue names no files, tests, or entry points. Start by locating the mini-block and full-zip encoding implementations and their format tests; done means CRC32 coverage exists for mini-blocks and individual values in the specified paths, with tests confirming checksum behavior.
