Teach the ASN.1 compiler the 'maps' option
When the 'maps' option is given, the SEQUENCE and SET types are represented as maps instead of as records. Optional and default values must be not be given as asn1_NOVALUE or asn1_DEFAULT in a map passed to the M:encode/2 function; they must be omitted from the map. Similarly, when decoding missing values will be omitted from the map. No .hrl files will be generated when the 'maps' options is used. That means values in an ASN.1 module must be retrieved by calling the appropriate function in generated module. Since we one day hope to get rid of the options 'compact_bit_string', 'legacy_bit_string', and 'legacy_erlang_types', we will not allow them to be combined with the 'maps' option.
