Changes made:
* Add Header.HeaderSize to track the actual size of the header.
The header is variable length, so providing this information allows
the caller to do other low-level tasks, such as determining whether
the entirety of a zstandard frame is a single segment block.
* Add Header.Skippable{ID,Size} to make the Header type more
useful for extracting data from metadata frames (see #459).
* Re-arrange fields in Header to better match the order
these appear in RFC 8478.
