10fe1c2636 Don't write Format for Coverage, ClassDef, Single/Alternate/LigatureSubst 
The format values for those are automatically handled in
postRead/preWrite to choose optimal format.  As such, don't write them
in XML.  Reduces noise.

move PaintFormat enum outside of Paint class nested scope 
When a TTFont is loaded with lazy=True, the otTables are only loaded upon BaseTable.__getattr__
when the requested attribute is not found in the instance __dict__.
Since the Paint.Format enum was defined at class level, every Paint instance, even when loaded
lazily, will have a 'Format' attribute and the magic decompile-on-missing-attribute will not
trigger, since the class attribute will be returned when the instance is missing one.

For this reason, and to not add further special cases, it's better to simply move this Paint.Format
enum class outside to the module level scope, and rename it PaintFormat.

add otConverter for namedtuples and use it for Variable{Scalar,Position,Distance} 
in COLRv1 all scalar values have associated varIdx to support variations. I want to load them as
immutable namedtuples, and also I want to dump them as simple XML tags with 'value' and 'varIdx'
attributes, instead of normal otTables (i.e. with nested Value and VarIdx sub-elements) as
that would make them too verbose in the XML dump.
So I made a custom _NamedTupleConverter, as a base class for VariableScalar, etc.; sub-classes
must provide a tupleClass and a list of converterClasses for each namedtuple field.

The ExtendMode enum has also a custom converter to dump it as string in the XML, and load it
as IntEnum.

set pre-initialized CountReference in VarRegionList.preWrite with fvar.axisCount 
so we can reuse CountReference class, as suggested in https://github.com/fonttools/fonttools/pull/1752#issuecomment-547113944

The patch is no shorter though.

[otBase|otTables] enforce VarStore RegionAxisCount == fvar.AxisCount 
even when there are no Regions and thus we can't take the length of VarRegionAxis array.
This is to appease older versions of OTS which blindly enforce this rule and
reject a VF that has, e.g., an empty HVAR table with no regions if the
HVAR.VarStore.VarRegionList.RegionAxisCount != fvar.AxisCount.

05f95f0f58 [otBase] Try ExtensionLookup if other offset-overflow methods fail 
If offset overflow happens other than between Lookup and SubTable, or
within SubTable, then we don't know how to fix it currently.  Now we
try to put that lookup in an Extension lookup anyway, since that will
isolate it and sharing with other lookups won't happen, hopefully
avoiding the overflow.

This is really a bandaid... What we want is the 99proof branch to
be finished and replace our current packing algorithm.
