Request a temperature report to be sent to the host at some point in the future.
Some hosts may hide the reply from M105.
A better way for hosts to get regular temperature updates is to use M155 (requires AUTO_REPORT_TEMPERATURES and EXTENDED_CAPABILITIES_REPORT). Hosts then no longer need to run an extra process or use up slots in the command buffer to receive temperatures.
