In JASN1Reader allow preprocess of ASN files to reconcile unsupported features

The ASN specification allows the creation of valid ASN files that has features unrecognized by the asn1bean library we are using in JASN1Reader.

We can add a preprocessing step that creates modified versions of the provided ASN files (leaving the originals intact) that removes unsupported features in a way that makes them less strict but otherwise should still be compatible with incoming data.

Identified unsupported features:

• Certain constraint types
  • E.g.

    SomeType ::= INTEGER (ALL EXCEPT (0..15))
    

• Extension marker (a.k.a "ellipsis" or

  ...
  

  )

• • Can occur in constraints (e.g.

    SomeType ::= INTEGER (0..8,...,100..200)
    

    although

    SomeType ::= INTEGER (0..8,...)
    

    works)

• • or in type definitions (e.g.

    RootType::= SEQUENCE {
    	field1		INTEGER,
    	field2		INTEGER,
    	...,
    	field3      INTEGER
    }
    

    but this seems to work as well).

• Version brackets e.g.

  SomeType ::= SEQUENCE {
  	integerField1		INTEGER,
  	integerField2		INTEGER,
  	...,
  [[ -- from version 2
  	integerField3		INTEGER,
  	integerField4		INTEGER ]]
  }
  

  Seems to require extension marker as well.
