Documentation (ICD) Generation and Performance Improvements

This new release improves the ICD (Interface Control Document) generation as well as the parsing performance:

• A new command line flag allows to select which ASN.1 types you want to see in the ICD (by default: all of them)
  e.g. asn1scc -icdAcn icd.html -icdPdus "TELECOMMAND,TELEMETRY" dataview.asn will generate the ICD only for the types named TELECOMMAND and TELEMETRY (and all their dependencies)
• The hyperlinks to the ASN.1 and ACN grammars have been fixed
• Various cosmetics improvements to improve the clarity of the tables (e.g. comments for ACN-inserted fields)
• To smoothen the transition, the new ICDs are generated in a file with the _new.html suffix (the prefix being the ICD name given in the command line).
• Major parsing performance boost
