The client should acquire resources to be associated with the file transfer. Incoming file transfers start in
the PAUSED state. After this callback returns, a transfer can be rejected by sending a TOX_FILE_CONTROL_CANCEL
control command before any other control commands. It can be accepted by sending TOX_FILE_CONTROL_RESUME.

Set the callback for the `file_recv_chunk` event. Pass NULL to unset.
This event is first triggered when a file transfer request is received, and subsequently when a chunk of file
data for an accepted request was received.
:param callback: Python function.
When length is 0, the transfer is finished and the client should release the resources it acquired for the
transfer. After a call with length = 0, the file number can be reused for new file transfers.
If position is equal to file_size (received in the file_receive callback) when the transfer finishes, the file
was received completely. Otherwise, if file_size was UINT64_MAX, streaming ended successfully when length is 0.
