splitting logic handling all asn.1 types (tagged / untagged)

[SNidhal]

the current version handles only files based on sequence or set types and the separator is using only two byte the first for the tag number and the second for length witch is not always the case

1. modifying the Jasn1 class generation method to add methods that returns the needed parameters :

• isTagged method returns if the main type is tagged or not
• getInternalTags method returns the list of internal tags (like in the case of choice type)

2. integrating the parameters in the splitting logic
