-------------------------------------+-------------------------------------
When trying to map and copy time_id3 metadata from a .ts file to a .ts
file, the time_id3 metadata is copied (e.g PRIV tags) but the ID3 header
is not inserted (x49 x44 x33).
ID3v2 header
The first part of the ID3v2 tag is the 10 byte tag header, laid out
as follows:
ID3v2/file identifier "ID3"
ID3v2 version $04 00
ID3v2 flags %abcd0000
ID3v2 size 4 * %0xxxxxxx
https://id3.org/id3v2.4.0-structure
