Add support for subsequent author substitution

[Drodt]

Fixes #219. Fixes #229 (as a first approximation)

Also fixes the error that affixes for bibliography layout were ignored. And updates archives.

Adds 96 tests to citeproc-pass.txt.

Still a draft until:

• [x] Code is reworked to be a bit nicer
• [x] Tests for bibliography are supported (See #229).
• All relevant tests pass:
  • [x] name_SubsequentAuthorSubstituteSingleField
  • [x] name_SubstitutePartialEach
  • [x] name_SubsequentAuthorSubstituteMultipleNames
