RPD plugin address block parsing

With the current version of the RPD plugin, when defining an address block and choosing the "US Address" option, the parsing of the address block is perfect when having a 5 digit zip code and when having a 5 digit zip code followed by a hyphen and plus4 (11111-2222). Unfortunately this isn't the case if the hyphen is missing (111112222) which results in failure to parse this address block correctly in the "US Address" format. It would be good to have RPD plugin be able to deal with this case.
