- added parameter 'initialize-parser' (default to nil), to reset
parser state in 'sexp->text-rows'; - added 'add-metadata-to-parsed-gemini-lines' This function will add attributes (like ':header-group-id') to the sexp representation of a gemini stream (structure: (tag ((attribute-key attribute value)...) text line) ) - [JSON-RPC API] added a couple of public API function.
