5508e7bf8a libavcodec/j2kenc: Allow Encoder to use SOP and EPH markers 
This patch allows the encoder to use SOP and EPH
markers. This would be useful as these markers
provide better error detection mechanisms.

This fixes a TODO item and unifies both decoders structures
It also fixes undefined behavior due to aliasing violations

I choose 2 fields instead of a union because mistakely using the
wrong type with a union will lead to hard to debug "wrong output"
while with 2 fields mistakely using the wrong type will crash
with a null pointer derefernce which is much easier to debug
