Remove fallback options from cache states #372

Closed whitfin closed 2 months ago

whitfin commented 2 months ago

This fixes #371.

This will remove :fallback from the cache state, as well as the ability to add state to fallback functions. This simplifies handling, removes error checking in favour of guards, and makes the cache state smaller to copy.

If people require that :state be added back in future, this is not off the table and has been documented as such. I am fairly confident that it will not be required due to it being kinda anti-OTP (most people will have separate processes for their state, so they can just use the :name).
