Support "emend." and "emend"

[dimus]

Word "emend." is an abbreviation from "emendatum" or "rectified by". It is introduced when one author refines work of another author. Normally "emend." would be with a dot, but sometimes dot might be forgotten. The treatment of "emend." is quite similar structurally with "ex, in". And example from biodiversity ruby gem:

Cleome kermesina Gilg & Gilg-Ben. emend. Kers var. plebeia Kers|{"scientificName":{"id":"291ce8f1-0e40-5ed5-afbf-a7a11b0bba59", "parsed":true, "parser_version":"test_version", "verbatim":"Cleome kermesina Gilg & Gilg-Ben. emend. Kers var. plebeia Kers", "normalized":"Cleome kermesina Gilg & Gilg-Ben. emend.

Possible variants:

Cleome kermesina Gilg & Gilg-Ben. emend. Kers var. plebeia Kers
Cleome kermesina (Gilg & Gilg-Ben. emend. Kers) Kers 1888
Cleome kermesina (Gilg & Gilg-Ben. emend. Kers) Kers emend Roskov 2000

@dimus do you think it could be simply added to the rule?https://github.com/GlobalNamesArchitecture/gnparser/blob/4dc7388c56c808488003ee8712ac4bf640e95198/parser/src/main/scala/org/globalnames/parser/Parser.scala#L505

It has the same context as authorEx, but it is semantically different. Better to introduce separate rule
