Missing imperial volume units

[bsidhom]

The prelude does not seem to include the imperial fluid ounce, imperial pint, imperial gallon, etc., but does have the US customary counterparts.

It would be nice to add these definitions, but I'm not sure how to deal with naming. We should try to avoid confusion as much as possible.

Note that this is unrelated to #116; I'm talking about individual unit definitions differing between US Customary and British Imperial. As far as I'm aware, this discrepancy only exists in volume units, but I'm not sure.

I suggest we follow Qalculates naming here, which has imperial_ prefixes for long unit names and UK_ prefixes for short unit names. For example:

imperial_gallon
UK_gal

Re: #382: after reading up on this, I just discovered that there's the customary tablespoon and "metric tablespoon" (15 mL exactly): https://en.wikipedia.org/wiki/Tablespoon. They apparently use metric tbsp in the UK. Not sure if this is worth adding or where to put it. Nobody appears to call it an "imperial tablespoon". There's a similar situation for the teaspoon.

Can you please open a new ticket?
