Feature description

If you activate debug srt by creating an empty file called debug_info_in_srt.txt on sc card the contents of the SRT file changes and is no longer accepted, making it impossible to render OSD.

An easy change would probably making SRT optional and just skip it when in debug mode. Or you could render some parts of it, like done for original SRT, however its more data so it likely will not fit.
