2000f47ae5 [set] Compute is_subset by comparing pages. 
Test subsets one page at a time instead of by codepoints. On my machine
this is about 250x faster than the previous implementation.

a08900b721 [subset] fix failing colrv0 subsetting when font has composite glyphs. 
Composite glyph collection was happening along side colrv0 glyph collection which meant it was possible to miss grabbing the component glyphs for a glyph added by colrv0.

56ca435787 [subset] fix for collect_features and remove_redundant_lamngsys 
previously remove_redundant_sys () is missing in harfbuzz, after
redundant langsys removal, some features are removed as well in
prune_features() in fonttools. This change is trying to get the same
result between harfbuzz and fonttools.

190b7a98f8 [subset] Update PairPosFormat2 subsetting to match fontTools updated subsetting (https://github.com/fonttools/fonttools/pull/2221) 
- subset class def 1 against the coverage table.
- Don't re-use class 0 in class def 2.
- Ignore class 0 glyphs for the purposes of determing format 1 vs format 2 encoding for ClassDef.

Add an additional test case which demonstrates these issues.

[ot] Keep substituted Default_Ignorables (#2886) 
Don’t replace Default_Ignorables with zero-width space if they are
substituted or multiplied, not just when ligated.

After this change, HarfBuzz output matches that of Uniscribe and
CoreText for the new tests.
