In favor of separate VARC table.
ttGlyphSet does NOT yet know how to draw VARC table though.
The 9 failing tests are all VarComposite-related and need
to be updated with VARC equivalents eventually when we
add VARC support to subsetter and instancer.
Fixes#2576
This updates our woff2 encoder/decoder to support retaining the OVERLAP_SIMPLE glyf flag following the updated WOFF 2.0 specification and official google/woff2 implementation.

* Replaced all from ...py23 import * with explicit name imports, or removed completely when possible.
* Replaced tounicode() with tostr()
* Changed all BytesIO ans StringIO imports to from io import ..., replaced all UnicodeIO with StringIO.
* Replaced all unichr() with chr()
* Misc minor tweaks and fixes
Note UI change : `fonttools varLib.models` now takes prefixed options `-d` or `-l` instead of guessing the intended feature from the number of arguments.
We have a number of command line tools which are somewhat opaque. (varLib.models in particular was very confusing.) This ensures that they all use argparse to have a consistent interface, and all have --help documentation which at least details their parameters, and hopefully therefore gives more of a clue about what they do. Those which use logging have had a command-line logging parameter added.
This adds a `help` verb (and `--help` option) to the `fonttools` command line tool. Submodules will be listed in the help text if they have an importable `main` function with a docstring, and `main`'s docstring will be used as the one-line description for the help text.
Fixes#1650
A regression was introduced with 3.43.0 when doing pyftsubset --flavor=woff2
and the input font is WOFF 1.0, thus it has a non-None flavorData already
but doesn't define the transformTables attribute.
Also, the TTFont.getGlyphOrder() automatically makes up a dummy
glyph order from the maxp.numGlyphs, we simply need to ensure
'maxp' is decompiled before 'glyf'.
When transforming glyf, the glyf.glyphOrder is guaranteed to
be present (as the glyf table has been already decompiled), so
we don't need to deal with it being missing or incorrect
(hence removed spurious tests).
Using TTFont.getGlyphOrder() would also require to decompile post and cmap tables.
But we don't need the actual glyph names in order to apply the WOFF2 glyf transform.
