class Depix::Binary::Fields::R32Field
real32 field. Now, there is some lap dancing to be done here. The DPX
files in the wild define nonexistant data as a charfield with all it's bits set (four times 0xFF byte). This is easy to verify with a string but practically useless once the charfield has been unpacked into a float. Therefore we first unpack the value as a charfield, then we check whether it's all blanking, and if it is we return nil. If it's not “all bits set” though what we will do is try to decode it again using the real float unpack pattern. The same dance happens reciprocally when repacking the data.
