asn1ct, asn1ct_gen: Eliminate unused exports
Stop export functions that are not called from outside their module. If the functions are not used at all, remove the functions too. The unused exports were found by running: xref:start(s). xref:add_application(s, code:lib_dir(asn1)). io:format("~p\n", [xref:analyze(s, exports_not_used)]).
