    ber: avoid deep recursion for constructed strings
    
    Bound the recursion depth to avoid a stack overflow while parsing a
    deeply nested constructed string.
    
    Call chain before this patch:
    
     - dissect_ber_octet_string
       - dissect_ber_constrained_octet_string
         - reassemble_octet_string (called for constructed types)
           - dissect_ber_octet_string *recursion*
    
    After this patch, the reassemble_octet_string will throw if the maximum
    recursion depth is reached.
