dataProvTables: Build a table of data providers for bee occurrence records
Description
This function will attempt to find and build a table of data providers that have contributed
to the input data, especially using the 'institutionCode' column. It will also look for a
variety of other columns to find data providers using an internally set sequence of if-else
statements. Hence, this function is quite specific for bee data, but should work for other
taxa in similar institutions.
