MH-Z19B allows to enable/disable 'automatic baseline calibration',
which is enabled by default (MH-Z19B v1.2 datasheet).
It operates on too short 24hr interval. So if the place
where sensor is located is not ventilated well "every" day, ABC will
make sensor under-report CO2 value, since baseline (400ppm) is moved
to lowest observed value in 24hr.
With such short recalibrartion window, sensor often doesn't show
correct CO2 levels when ABS is left enabled. Disable it on boot
defaut and add 'automatic_baseline_calibration' option to allow
override from config.

it will allow to report exact sensor type in dump config
and later will be used for turning off autocalibration.

Reported CO2 might be not correct while sensor is booting and
while it boots it reports value 15000 in response at offset
6-7. So skip reporting till this value is being reurned.

When sensor is connected to hardware uart, sometimes on boot
uart's RX buffer contains several bytes of junk. Workaround it
by draining all of it before sending command.
Also turn on cleanup logic only if problem is detected (i.e.
when reply from sensor doesn't look correct.

update() is supposed to deal with reading and updating CO2/Temp,
while response checksum verification applies to other responses
as well.
Move check into mhz19_write_command_() that handles communications
with sensor.

it should help with debbuging issues if debugging is enabled.
Also it adds buffer dump function that will be used later
to dump invalid responses.

per spec request and response are of the same length,
simplify code by using the same length buffers. It should
help later when more code that uses buffers are added.

flush() is used to flush TX buffer, but there weren't anything
written to TX yet, so it's pointless to call flush() so early.
Remove unnecessary call.
