Crate temp_file_name

This is a tiny crate with one purpose: generate temporary filenames from a hash of arbitrary data so that they are consistent across different crates. Its intended purpose is to either

• give a consistent name, which can -- for example -- be used to cache the expensive output of an input across runs,
• or to allow a caller to know what filename a different crate will have given some abstract data.

It would be trivially easy to replicate; it exists primarily to allow consistency across otherwise unrelated crates when handling data
