As a User I want parser to work with 'ex', 'ab.', 'ab. n.', 'cv', 'st'

[dimus]

Looks like we have quite a few names with ex and ab, but I do not know how to handle them correctly. We need to ask around

Acidalia remutaria ab. n. undularia
Acmaeops (Pseudodinoptera) bivittata ab. fusciceps Aurivillius, 1912
Acanthochiton ex quisitus
Acastella ex gr. rouaulti
Androlepis skinneri Brongniart ex houllet
Phyllostachys vivax cv aureocaulis
Rhododendron cv Cilpinense
Ligusticum sinense cv 'chuanxiong' S.H. Qiu & et al.
Crematogaster impressa st. brazzai Santschi 1937
Cibotium st.-johnii Krajina
Camponotus conspicuus st. zonatus

ab. is a legacy rank in zoology, "Abberation"

cv, cultivar is for a cultivated plant name. The code recommends to use single quotes around the cultivar name, normally capitalized

Acastella rouaulti is an existing Trilobite species, but could ex gr. just be digitization errors?

Acanthochiton ex quisitus looks suspicously like exquisitus

Androlepis skinneri Brongniart ex houllet is for the ex author Houllet: https://de.wikipedia.org/wiki/Androlepis_skinneri
