[Feature] A way to convert imperial to metric within stash

[pr0user1234]

Is your feature request related to a problem? Please describe. Sometime data sources are only in imperial (lbs, height in inch) and you have to convert it manually to be consitent with stash-db would be nice to add directly and let stash convert it

Describe the solution you'd like a toggle to write imperial (lbs, inch) and stash converts it, same with messurements (cup size) to imperial if the datafields are split in future.

For scrapers its not a problem, but if you happen to stumple upon a messurement in the twitter bio, on the agency site, mentioned in a scene (e.g. fit18) etc. its a little bit annoying to convert.
