#527 MXF SMPTE Labels for st2086 metadata

[cledwyn4]

As well as identifying the transfer characteristics for an mxf master file, it would also useful to be able to easily identify the master display characteristics, as stated by st2086 metadata values.
These are optional, and when present, held in the Generic Picture Essence Descriptor
The expected Item ULs are as follows:

Mastering Display Primaries
Item UL as specified in IMF App 2E st2067-21-2016: 060e2b34.0101010e.04200401.01010000

Mastering Display White Point Chromaticity
Item UL as specified in IMF App 2E st2067-21-2016: 060e2b34.0101010e.04200401.01020000

Mastering Display Maximum Luminance
Item UL as specified in IMF App 2E st2067-21-2016: 060e2b34.0101010e.04200401.01030000

Mastering Display Minimum Luminance
Item UL as specified in IMF App 2E st2067-21-2016: 060e2b34.0101010e.04200401.01040000
