Where is tare flow ? #24

Hello Ahmad,

Current our version of the driver does not have any way to tare flow. I haven't tested it myself, but believe @marinapalese implemented it in her fork. It's also possible to tare flow from the front panel.

Thanks @alexrudd2! Yes it is the tare_volumetric() function. The serial command it uses has existed for all mainline firmware, and I've tested all the code I wrote. Taring from the front panel depends a bit on the firmware - older controllers you had to fiddle with the auto tare for a one-time tare.
