Jonathan Bernard 35377f5a25 Fix vCard 3 inline binary round-tripping
Decode ENCODING=b payloads for PHOTO, LOGO, SOUND, and KEY when parsing
so serializing a parsed card does not base64-encode already encoded wire
data a second time. Add regression coverage for both inline binary and
VALUE=uri round-trips.

VCard

nim-vcard is a pure nim implementation of the VCard format defined in RFCs 2425, 2426, and 6350. It allows you to parse and serialize VCards, as well as create VCards programmatically. It aims to be a complete implememtation, supporting all of the features of the VCard3 standard. Because the standard provides many features that may be rarely used, this library also provides a simplified API for more typical use-cases.
