Use of plm_buffer_create_with_callbacks without PL_MPEG_IMPLEMENTATION

[thennequin]

Hi,

I want to to se plm_buffer_create_with_callbacks for custom file loading, but plm_buffer_t struct is not usable without defining PL_MPEG_IMPLEMENTATION. So I wandering if we can pass necessary informations (memory pointer, size to load and size loaded) to load callback to just read data without changing the buffer struct. Or maybe exposing plm_buffer_t struct publicly.

Thanks and great works on your libraries :)
