fixup previous commit
even if none of the referenced regions in this VarData are dropped we may still
have to apply the scalars...

refactor and simplify instantiateItemVariationStore
we can reuse the prune_regions method defined in varStore.py to update
the VarRegionList.

also update the counts at the end (will be done automatically on compile anyway).

instancer: enumerate fvar axis indices only once then look them up
fvar axis tags are unique, we can compute the mapping from tag to index
once and reuse when we need them index from the tag.

Makes it more readable

instancer: round MVAR deltas at the end
and don't use enumerate() when iterating over region axes, as get_support() method returns a dict

bb667f6841 rename applyCvtDeltas to setCvarDeltas

62c98b451a instancer: share same instantiateTupleVariationStore for both gvar/cvar
refactored code, hopefully simplifying things a bit.

for cvar/cvt we do the rounding only at the end after we have summed the scaled deltas
to avoid introducing unnecessary rounding errors.
