Left Mode Justify
This mode embeds audio after EAV. The audio is embedded as specified
group number (EMBED_GROUP), and any existing auxiliary data
packets (ADP) not using the ADS area used by the audio groups is kept
(if an ADP is located just after the EAV, it is overwritten with the new
embedded audio group).
Fragments may remain in the ADS if the audio group partially
overwrites an existing ADP. This is not a problem for most De-Muxes,
but may cause odd behavior in some equipment.
EMBED_GROUP will not be embedded and an error will be reported if
the group specified already exists in the ADS.
