fix(mp4): keep moov children in file order when decoding

Decoding added each child with MoovBox.AddChild, which moves a trak
that follows an mvex or other box next to the previous trak. That suits
building a moov, but on decode it reordered the file's boxes, so a
decoded moov did not re-encode to the same bytes.

Decoding now keeps the children as decoded and only sets the child
fields, which AddChild also uses.
