Update mime-db update 1.53.0

[fonsp]

Updated the db to 1.53.0

Used an OrderedDict implementation to match https://github.com/jshttp/mime-types (this was the original intention)

With the new db, there was one change: .mp4 went from video/mp4 to application/mp4... I'm not happy with that buy maybe it's not about what makes me happy?

This also happened in the js lib: jshttp/mime-types#119 (comment)

But reading the RFC that defines the mimes makes me believe that video/mp4 is in fact a better default, application/mp4 is not more general: it is only meant for mp4 files without video or audio content.
