It is not mandatory and prevents breakage on rename.

Those chunks don't need to be parsed and they weren't parsed correctly
by Doxygen anyway.

This simplifies useage for users who are used to vpxenc.
We continue to support the previous options with the exception of the flags

This fix is not ideal as it still limits the multithreading on field pictures
to the 2nd field only.
Ill try to fix it properly to allow both fields to decode concurrently but this
needs more work.

Read the key in the first, value in the second.

This allows to avoid pointless strdups and simplify decode_str() by
dropping two of its parameters.
