While logging output live to a pcapng file, I'm interested to implement a log limit based on the output file size. So I would like to be able to call a light_io.h function to get the file size. Eg maybe light_io_get_size() or light_io_tell().
struct light_file_t could have a fn_tell function pointer added to it.
In the case of light_io_file.c, it could be implemented with return ftell(file).
I'm not sure what would be a good implementation for light_io_zlib.c etc.
Note, I see there is a light_file_seek() which is not used in fd->fn_seek.
