9e1bd2d0b4 Implement FeatureParams 
All types of FeatureParams are correctly handled now.

The only thing not handled is broken fonts generated with the
old AFDKO that have their FeatureParams offset computed wrong.
I don't currently plan on handling those.

58acba2d02 Remove "optimization" re Extension lookups 
Historically, Extension lookups were only decompiled upon access,
and decompiled Extension lookups were possibly copied verbatim to
output when compiling.  This discrepancy with all other table types
is confusing and undeed.  The possible time saving is not worth the
loss in possible optimization of table data.  Remove.

078b36325d Instead of countVars, pass down tableDict

get propagated down.

41caf2dea1 Remove tableStack in favor of countVars 
We only needed tableStack to look back for counts.  So, just store
counts.  Gives ~8 speedup for large fonts I tested.  We are not
faster than not loading fonts lazily without this patch, so the
laziness patch combined with this doesn't have a net negative
performance impact anymore.

f50d0dff86 Load all OpenType sub-structures lazily 
Huge win for subsetter and anyone else who doesn't need the entire
tables.  Subsetting a huge font (eg. NotoSans-Regular.ttf) to a
small set (say, main Cyrillic characters) is something like six
times faster now.  Bulk of time was being spent in blowing up the
GPOS kerning pairs and attach points.  Now we don't load those if
they won't be in the final subset.

Slight slowdown for usecases that need the entire table.
