asn1_erl_nif.c: Correct handling of tags >= 16384
Tags number above 16383 were not decoded correctly in
ber_decode_tag().
We could fix the problem, but there does not seem to be any need.
First, the only way that high tag numbers can be created is with
manual tagging; after 1994 manual tagging is no longer recommended.
Second, the ASN.1 playground (http://asn1-playground.oss.com) only
supports tags up to 16383 (the same is presumably true for OSS
Nokalva's other tools).
Therefore, clean up the existing code and make it an explicit
'invalid_tag' error when tags above 13383 are encountered
(instead of an implicit 'wrong_tag' error).
