Add missing definitions to type status vocabulary

[MattBlissett]

GBIF's API has additional type status values which are not in the vocabulary here.

We are missing:

• hypotype
• homeotype
• plesiotype

The definition of these terms in unclear to me. http://mailman.nhm.ku.edu/pipermail/taxacom/2000-November/084885.html says a plesiotype is the same as a hypotype, but https://micropal-basel.unibas.ch/Colls_NMB/GENERALS/COMTYPES.HTML says a plesiotype isn't a type at all.

This needs input from a taxonomic expert.

I read the "non-type" types like Pleasiotyps as being a category for specimens not being relevant to nomenclature (therefore non types), but using a similar definition for specimens of higher value to the public cause they have been depicted in a publication for some other reason.

I also found people categorising the kind of types as primary, secondary and tertiary types. Primary directly describing a name, secondary I am unclear, possibly potentially describing specimens in the future? and tertiary for the "non types" that do not have any nomenclatural value at all. We will ask the COL Taxonomy Group for input
