18886da333 [voltLib] Use NamedTuple for pos 
Using a plain tuple here is ugly, it should have been another ast class,
using NamedTuple to not break backward compatibility. Needed for next
commit.

91cb76554d [voltLib] Handle ALL and NONE in PROCESS_MARKS 
Both were treated as group names, as NONE was not checked at all and
code for ALL was never reached.

cedf79b505 [voltLib] Return a tuple from parse_coverage_() 
This is a followup to commit 94633e9f46975c356ec3a2d21ed30768c2fa0cd5,
where I mistakenly made it return an Enum but parse_coverage_() it not
used only for ENUMs and in many (most?) places returning an Enum is
wrong as you have a list of separate items that has to rmain separate.

b6ec12bad0 [voltLib] Distinguish different PROCESS_MARKS 
PROCESS_MARKS followed by a group name is used for markAttachmentType
lookup flag, while followed by MARK_GLYPH_SET is used for
useMarkFilteringSet. The code parsed both correctly but did not
distinguish between the two in the generated AST as it should since they
compile to different lookup flags.

4236772ec1 [voltLib] glyphSet() should return tuple 
We need to maintain the glyph order and keep any duplicates.

94633e9f46 [voltLib] Fix parsing glyph groups 
* Fix ast.GroupDefinition.glyphSet() by using ast.GlyphName,
  ast.GroupName and ast.Range in Parser.parse_coverage_(), and making it return
  ast.Enum.

* Add ast.Enum.__len_() to fix the calculation of max_src and max_dest
  in Parser.parse_substitution_(). I’m not sure I understand the logic
  of this many to many check, will double check later.

* Update the test suite to reflect this. Had to add ast.Enum.__eq__() to
  make it less painful, and __hash__() as otherwise ast.Enum wouldn’t be
  used as a key in dicts (not sure this is a goo idea either, will
  double check later).

e529832362 [voltLib] Don’t try to read past END 
The parser was still trying to read the next token even when the current
token was END, but I think it should just stop reading here. When
reading from TSIV table there can be null bytes at the end when would
cause an exception in the lexer.

ca716e0925 [voltLib] Fix check for duplicate anchors 
When checking for duplicate anchors, the component number should be
taken into account since the same anchors can be used for different
components i.e. over ligatures.
