The implementation permits to read from a buffer or from a file.
To read from a buffer, we should call create_reader_buffer.
For a file it's create_reader_fd.
The underlying method called to effectively read from the source is hidden. To read with a t_reader we just may call reader_read with a pointer to the t_reader, the destination buffer in which we want to write the data, and the length of data we want to put in destination buffer.

It closes #2 issue.
