Added settings for Meter Pro Co2

[ahrmn]

I reverse-engineered the settings of the Meter Pro (CO2) and implemented them here.
I have no means of testing if this work for the other Meter models.
An example script to fully configure a device using this would be for example

import asyncio

from switchbot.devices.meter import SwitchbotMeter
from switchbot.discovery import GetSwitchbotDevices
from switchbot.const import SwitchbotModel

BLE_MAC='XX:XX:XX:XX:XX:XX'
METER_MODEL=SwitchbotModel.METER_PRO_C

async def main():
    switchbotDevices = await GetSwitchbotDevices().discover()
    meter_advertisement = switchbotDevices[BLE_MAC]
    print(meter_advertisement.data)
    meter = SwitchbotMeter(device=meter_advertisement.device, model=METER_MODEL)
    await meter.sync_time()
    await meter.show_battery_level(False)
    await meter.set_date_format(True)
    await meter.set_time_format(True)
    await meter.set_co2_thresholds(900, 1200)
    await meter.set_comfortlevel(19, 22, 40, 70)
    await meter.set_temperature_update_interval(10)
    await meter.set_co2_update_interval(10)
    await meter.set_button_function(False, False)
    await meter.set_alert_sound(False, 2)
    await meter.set_alert_temperature_humidity(True, 17, 28, False,
                                               True, 40, 70, False)
    await meter.set_alert_co2(True, 400, 1200, False)
    
asyncio.run(main())

Additionally one can trigger a new measurement regardless of the frequency using
await meter.force_new_CO2_measurement() and calibrate the sensor (at fresh air!) using
await meter.calibrate_co2_sensor().

This may solve #416.
@jacekowski Can you test if this synchronises time for the Meter Pro (without CO2 sensor)?
