MIME registry is coming to Crystal's stdlib

[straight-shoota]

I want to give a heads up: MIME database API has been merged into Crystal's standard library and will probably be included in the next release. See crystal-lang/crystal#5765 for details.

I guess this could make this shard mostly obsolete, typical use cases should be covered by the stdlib implementation.
There are some differences: it doesn't read a JSON file but the mime.types format (which commonly used by MIME applications). And it doesn't ship with a copy of this database by default, relying on a list provided by the operating system.
These differences are IMO not very relevant. It's quite trivial to switch to mime.types format (this is the de-facto standard anyway) and bake the file into the binary (if required).
