primary table of tables that decode:
	lang -> language tags and names
	script -> ISO 15924 script tags
	region -> ISO 3166 region tags
	variant -> iana registered variant tags
	suppressed -> map of scripts tags and their associated language tags
	
all of these data come from separate modules that are derived from the IANA language-subtag-registry file

key_to_lower avoids the metatable trap and sets all keys in the subtables to lowercase. Many language codes
have multiple associated names; Module:lang is only concerned with the first name so key_to_lower only fetches
the first name.

TODO: instead of returning:
	["key"] = {"name"}
where each table has only one name, return
	["key"] = "name"
requires changes in Module:Lang.
