Add a third config for Beca BHP6000 thermostat quirks.

Issue #215

When set to C, the temperature in the protocol seems to start equal to
F at the bottom of the range, and go up by 0.5 for every 1 increment,
so by the top of the range has drifted away from F by about 4-5
degrees.

A third config has been added to handle this rather than replacing the
existing C config, as it is a bit strange and may be due to a firmware
bug in a specific version of the thermostat.

+Some of these devices support switching between Celcius and Fahrenheit
+on the control panel, but do not provide any information over the Tuya
+local protocol about which units are selected.  Three configurations
+for BHP6000 are provided, `beca_bhp6000_thermostat_c` and
+`beca_bhp6000_thermostat_f`, which use Celsius and Fahrenheit
+respectively, and `beca_bhp6000_thermostat_mapped` for a buggy looking
+firmware which displays the temperature on the thermostat in Celsius
+in increments of half a degree, but uses a slightly offset Fahrenheit
+for the protocol, as detailed in issue #215.  Please select the appropriate
+config for the temperature units you use.  If you change the units on the
+device control panel, you will need to delete the device from Home Assistant
+and set it up again.
