    h263parse: fix custom picture format (CPFMT) parsing

    In the H263 spec, CPFMT is present only if the use of a custom
    picture format is signalled in PLUSEPTYPE and UFEP is "001",
    so we need to check params->format and only if the value is
    6 (custom source format) the CPFMT should be read, otherwise
    it's not present and wrong data will be parsed.

    When reading the CPFMT, the width and height were not
    calculated correctly (wrong bitmask).
