Add the strong_id crate as a Rust implementation of TypeID (#93)

I have a Rust crate which implements TypeID-like behavior for unsigned
ints and UUIDs. It is compliant with the TypeID spec when the "typeid"
feature is enabled, which is the same as enabling both "uuid" and
"uuid-v7" features.

I've included a dedicated crate which pulls the spec files and tests
encoding/decoding the values:
https://github.com/johnnynotsolucky/strong_id/tree/main/tests/typeid_spec

There is also a github workflow which runs on a 6 hour cron to confirm
that the implementation is still valid:
https://github.com/johnnynotsolucky/strong_id/blob/main/.github/workflows/typeid_spec.yaml

This crate takes a different approach in that it uses macros to generate
TypeIDs so that we can have compile-time validation of prefix rules.
