ts_51_011, utils: fix Access Technology Identifier coding

When the Access Technology Identifier encoder sets the bits for E-UTRAN
it does not respect that bit "100" is also a valid bit combination that
encodes E-UTRAN WB-S1 and E-UTRAN NB-S1. Lets encode this bit
combination if the user is just specifying "E-UTRAN" without further
spefication of WB or NB.

The decoder only looks at bit 14 and decodes "1xx" always to "E-UTRAN".
This is not specific enough. Lets make sure that the decoder is
complementary to the encoder.
