ShortCaseCitation.full_span now includes parentheticals

[varun-magesh]

Previously, only FullCaseCitation objects included parentheticals and antecedent text in the full_span method.

For example, in this ShortCaseCitation:

>>> test_sentence = "See Sargent, 75 F.3d at 89 (explaining that blah blah blah)."
>>> eyecite.get_citations(test_sentence)[0].full_span()
(13, 26)

However, if the same citation was a FullCaseCitation, what is included differs:

>>> test_sentence = "See Sargent v. Columbia Forest Prods., 75 F.3d 86 (2d Cir. 1996) (explaining that blah blah blah)."
>>> eyecite.get_citations(test_sentence)[0].full_span()
(4, 97)

I am working in an application that requires all full_span definitions to be more like the latter, so I've made a small set of changes to ShortCaseCitation, IdCitation, and SupraCitation.

No existing tests seem to break, but I have not written new tests for the changed behavior.

If this is desired behavior; that is, if it would be helpful to harmonize these definitions by always including the parenthetical and antecedent, I can write some tests and clean this up a bit into a PR. Let me know if that would be helpful.

Makes sense to me. Thank you!

I agree, this behavior should definitely be the same for full vs. short/supra/id citations.
