DS file header should include additional metadata

[skliper]

DS currently stores a number of fields in the DS file header (DS_FileHeader_t), namely the time the file was closed, the file name, the file table index, and the file name type.

When reading DS-created files on other platforms with other configurations, it is possible to tease apart platform/mission-specific information but it would be easier to store the configuration in the header for easier analysis of DS files.

Additional information should include, at least, the CCSDS time format (CFE_SB_PACKET_TIME_FORMAT), the CCSDS secondary header (CC, timestamp) endian-ness, byte alignment, even the DS file header endian-ness for the close timestamp.

Also, as this will break compatibility with any DS-generated files from previous versions, including a DS header format version # should be included.
