New measure: refillable inhalers

Deprioritised for the moment but saving as a record when we get time

#4003

There appears to be some inconsistency in naming of some inhalers in dm+d where both device and refill versions exist.

For example:

Olodaterol 2.5micrograms/dose inhalation solution cartridge CFC free
vs
Olodaterol 2.5micrograms/dose solution for inhalation cartridge with device CFC free

Therefore using partial string matching (everything prior to the "with device") would not identify the refill in this case, or some others.

As there's no flag for a refill in dm+d, and given the difficulties of manually curating these products in a fast-changing environment, we'll have to pause development for now. I will email dm+d and ask if there's the possibility of an amendment, and to understand the naming rationale.
