Other drivers consider that they received data even if the value is
reported as "out of range" by sensor. On the I2C driver for TFMiniPlus
we considered this case, too. However when the signal strength is very
low (and thus the distance would likely be out of range), we would end up
ignoring the new sample. With enough samples without any value this
would lead the status to turn to "NoData".
On this version of the firmware the command changed - support the new
command and only that one: it's not expected to have devices with the
older versions.
