streamWrapper::stream_seek — Seeks to specific location in a stream
This method is called in response to fseek().
The read/write position of the stream should be updated according to the offset and whence.
The stream offset to seek to.
Return TRUE if the position was updated, FALSE otherwise.
If not implemented, FALSE is assumed as the return value.
Upon success, streamWrapper::stream_tell() is called directly after calling streamWrapper::stream_seek(). If streamWrapper::stream_tell() fails, the return value to the caller function will be set to FALSE
