`macsrc` and `macdest` matches values are improperly parsed

[lel-amri]

The rules compiler (featured in the official controller) automatically reformat MAC addresses to separate bytes with colon characters. For example, 0123456789AB becomes 01:23:45:67:89:AB. Matches macsrc (MATCH_MAC_SOURCE in JSON) and macdest (MATCH_MAC_DEST in JSON) are parsed in a way that doesn't ignore the : character, and treat it as if it was carrying address information (the current implementation treats it as a 0). In the end, the filtering engine doesn't get the valid MAC address and thus comparisons with packet MAC addresses fails.
