Formats current are represented by a list of Ods::Descriptor. Count of
fields is blobLength / sizeof(Ods::Descriptor).

I now want to encode it as follow:
	numberOfFields: USHORT
	list of Ods::Descriptor
	numberOfFieldsWithDefault: USHORT
	list of (<fieldId: USHORT><Ods::Descriptor><data: dsc_length bytes>)

Default values are read by MET_format and written by DFW/make_format.
EVL_field "clever" logic is replaced by the new logic that catch
defaults from the format.
