Efficiently convert selected columns of data.table to nquad statements

1	convert(dat, schema_list, type = "", datatype = "", done_so_far = 0)

`type`	Type of nquads statements: `'uri'` or `'literal'`.
`df`	Name of the data.table as a length one character vector.
`column_names`	Names of the data.table to be converted as a character vector.
`base`	Base of the URIs to be minted in `uriref`,
`paths`	Further path of URI to be minted in `uriref`.
`datatypes`	Character vector containing the datatype of literals. May include language statements.

the_data = data.table(refs = c('a', 'b', 'c'), ltrl = c(1, 2, 3))
convert(df = "the_data", column_names = "ltrl", type = 'literal', datatypes = 'xsd:int')
convert(df = "the_data", column_names = "refs", type = 'uri', base = 'https://www.example.org/', paths = 'data/')
print(the_data)
