Inconsistent annotations for LS entries

[rhdunn]

1. List items are annotated with the X UPOS. -- EWT favours NUM for these and https://universaldependencies.org/u/pos/X.html states that it should be used restrictively.
2. These should have the NumType=Ord feature (as they specify an ordered list of items).
3. The 1. etc variants should have the NumForm=Digit feature.
4. The a) etc variants should have a NumForm feature, but no suitable form currently exists for these; maybe NumForm=Alpha (alphabetic -- "Examples: a, b, c, α, β, γ").
5. EWT tokenizes the ( and ) as separate tokens.

I could see using Ord for the numerical ones, but until we sort out what we're doing about LS I will leave this open. I anticipate this will stay as-is for v2.13.

Ping regarding this ( and @nschneid) ... one of the more frequent errors caused by the CoreNLP constituency -> dependency converter is because it wants to make the dependency "num" but the UPOS "X". If we come up with a standard and apply it to the EWT & GUM treebanks, I can implement that in the converter pretty easily.

Yeah, we need a standard. It's under discussion in the core group.
