Ie, now we get:
...
assert 0 <= value < 0x10000, value
AssertionError: (None, 'LookupListIndex', 'SubstLookupRecord[0]', 'ChainContextSubst[1]', 'Lookup[3]', 'LookupList')
The common stacktrace like this:

assert 0 <= value < 0x10000, value
AssertionError: None
now has this as the last line:
AssertionError: (None, 'LookupListIndex', 'SubstLookupRecord', 'ChainContextSubst', 'Lookup', 'LookupList')
which means a value of None was tried for writing a LookupListIndex from a ChainContextSubset...
It's a hack, but a very useful one.
This reverts commit d8803873f6d4efbcb227867fe0ac6bca370597bc.
The commit wasn't fully correct as it was not installing properties
for counts in format-switching subtables.
Before, equivalent types, eg. otTables.BacktrackCoverage, etc,
where a subclass of their equivalent parent type, eg. otTables.Coverage
With this change, they are the same type.
The otBase and otConverters changes were needed to make the above
happen and still generate correct XML for SubTable type.
the third (2015) edition of ISO/IEC 14496-22 "Open Font Format" increased
the limit from 32767 to 65535 (and thus eliminated the reserved numbers).
`array.array` will take care of raising the right `OverflowError` exception
so we don't need any further checking.
Also removing unused stats collection. The need for setting up
an object to collect these (unused) stats made it hard to write
tests on code that called OTTableReader.getSubReader().
NameRecord.__str__ returns a unicode string, but on Python2 the built-in str()
expects a bytestring, therefore it raises
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)
We should probably change that as well.
If the referenced name record already exists, the string is modified in place.
If it doesn't exist, a new record is created with the given IDs and string.
If nTracks == 0, nSizes is also == 0, the `else` part is sufficient.
There's a limit case when nTracks can be > 0, and nSizes == 0, but it's
unlikely or useless.
