Read derived variables from other MIP tables

[bouweandela]

Description

If a derived variable is present in the CMOR tables, but not in the mip specified in the recipe, look it up in other mips. This avoids the need to create custom CMOR tables for such cases.

looking good, and thanks @bouweandela - glad to see Liza's case taken care of - the only thing I can think of as a potential vulnerability is if the user specifically doesn't want this to happen - maybe add the info (ie derived vars will not be looked up in other MIP tables) to the "CMOR strict" case documentation?

Thanks for reviewing ⭐ I just added a note.
