WIP: invert asn1ct tag workaround

The erlang asn1ct compiler runs into problems when a context specific ASN.1 tag is applied twice, which is the case in the original SGP.32 SGP32Definitions spec.

Currently we remove the excess tag on the ASN.1 struct definition. This works fine as long as the structs are only used internally, which is the case when ASN.1 ESipa bindings are used. When the JSON ESipa bindings are used, many of the structs are used directly. A missing context specific tag on the struct definition will then obviously cause interoperability problems.

With this patch we invert the workaround, we now no longer remove the context specific tag at the struct definition, instead we remove it at the struct member in each parent struct.
