[featureVars] allow to assign same subst lookup to several feature tags 
this can be useful to maximise layout engine compatibility or simply to have same feature variations substitutions be accessible via mutliple feature tags for whatever reason.

use 0 for sidebearing sparse metrics sentinel 
font sources only allow to specify advances, the sidebearings are computed. Makes more sense for the sparse metrics to have 0 for the sidebearings as the glyph that's meant to be 'sparse' is most likely empty with no outlines

varLib: add --drop-implied-oncurves option 
For the test, I used the Tests/varLib/data/Build.designspace as starting point, modified the 'a' glyph so that 1 on-curve point (the first one) becomes impliable for all the masters.

e5029801d2 support merging COLR masters with 'sparse' glyphsets or different layer count 
There is no longer a requirement that all the masters have exactly the same base color glyphs as the default masters. Similarly, it's no longer required that all masters' LayerLists have the same total count of layers. It is sufficient that, for a base color glyph in the default master, a non-default master may (or may not) contain one with the same name and same effective number of layers (which in turn can be laid out differently in the respective LayerLists).
This provides greater flexibility when working with variable font project with sparse glyph sets.

c397764720 COLRVariationMerger: implement reuse of VarIndexBase between tables with same varIdxes 
When multiple variable tables refer to the same delta-sets they can now share the same VarIndexBase so the resulting DeltaSetIndexMap is a bit smaller.
For simplicity, we only reuse VarIndexBase when variable tables fully share (ie. same, and same number of) varIdxes; potentially we could reuse subsets of varIdxes (e.g. a VarColoStop.Alpha has a +0.5 delta, and later on elsewhere a PaintVarSolid.Alpha has a similar +0.5 delta; the latter could have a VarIndexBase that reuses an existing DeltaSetIndexMap entry for the former), but for now this I think is good enough.

Add debug logger showing the glyph name for which gvar is built 
When building gvar, some situations cause fontmake/varLib to fail, for example if a component has a coordinate that's >32k or <-32k. This adds a debug line that prints each glyph name for which gvar is built, so it’s easier to pinpoint where the faulty glyph is.
