Remove check_species(), get_scientific_name()

[peterdesmet]

Suggested in camtraptor July 2023 coding sprint

The functions get_scientific_name() returns a vector of scientific names for provided vernacular names, within the scope of a package. It does not allow scientific name values:

> get_scientific_name(mica, c("bever", "mens"))
[1] "Castor fiber" "Homo sapiens"

> get_scientific_name(mica, c("bever", "mens", "Ardea")
+ )
Error: Invalid value for vernacular_name parameter: ardea.
Valid inputs are: mallard, gadwall, great herons, grey heron, eurasian beaver, human, beech marten, european polecat, red fox, wilde eend, krakeend, reigers, blauwe reiger, bever, mens, steenmarter, bunzing and vos.

The function check_species() returns a vector of scientific names for provided vernacular names and scientific names, within the scope of a package:

> check_species(mica, c("bever", "mens", "ardea"))
Scientific name of bever: Castor fiber
Scientific name of mens: Homo sapiens
[1] "Castor fiber" "Homo sapiens" "Ardea" 

We think these functions are no longer necessary:

• The current functions are confusing (what is their difference?)
• The current functions translate vernacular names to scientific names, but only based on the info that is available in a package. So one could not get a result because the species is not present or (worse) the species is present, but the vernacular name is not included.
• The suggested taxonomy() Update get_species() to taxonomy() #115 function provides an overview of taxa that are present in a (filtered) package in a tabular format. That information is easier to scan for existing (and missing) vernacular names that the current functions.
• The suggested filter_ functions Create filter_deployments(), filter_observations(), filter_media() camtrapdp#23 allow to search on any column, e.g. scientificName, vernacularName.nld etc. Having functions that convert vernacular names to scientific names are less useful here.

Agree. To be added to defunct functions.
