Hash suffix not a reliable identifier for caching

[donmccurdy]

We append a hash suffix to output files, e.g. scene.ba38z8.glb. The goal of the hash is that new deployments shouldn't invalidate caching of large files. However, the method used to compute the hash is imperfect — it's a binary hash of the input file.

It may be better to either hash the output file's content, or to hash a combination of the input file and the transforms being applied to it. Probably the former.

The hash can be disabled with the {hash: false} option.
