Add additional Netatmo public data sensors

[GP8x]

Description:

I updated the pyatmo library to expose additional conditions from the Netatmo GetPublicData API in this PR: jabesq/netatmo-api-python#15

This PR extends the HomeAssistant Netatmo Public sensor to monitor the following conditions:

• temperature
• pressure
• humidity
• rain
• windstrength
• guststrength

In order to change from a single value sensor to multi-value I made a breaking change to the configuration to add in a monitored_conditions list for each "area". At the same time I also changed the current optional type configuration property to mode as type to me didn't accurately describe the function the value performs (switching between avg and max sensor data processing). I realize breaking configuration changes are generally not a good thing but believe the above approach is more extensible for the future and better aligns the sensor configuration with other multi-condition sensors (e.g. Yahoo Weather).

Example entry for configuration.yaml (if applicable):

sensor:
  - platform: netatmo_public
    areas:
      - lat_ne: 40.719
        lon_ne: -73.735
        lat_sw: 40.552
        lon_sw: -74.105
        monitored_conditions:
          - temperature
          - pressure
          - humidity
          - rain
          - windstrength
          - guststrength

Checklist:

• The code change is tested and works locally.
• Local tests pass with tox. Your PR cannot be merged unless tests pass

If user exposed functionality or configuration variables are added/changed:

• Documentation added/updated in home-assistant.github.io

If the code communicates with devices, web services, or third-party tools:

• New dependencies have been added to the REQUIREMENTS variable (example).
• New dependencies are only imported inside functions that use them (example).
• New or updated dependencies have been added to requirements_all.txt by running script/gen_requirements_all.py.

Great 🎉

What is filtering?

[GP8x]

Filtering makes the API response exclude abnormal sensor readings. For example if someone installs an outside sensor indoors.

@colinfrei Any comments?

[MartinHjelmare]

We should use None to represent unknown state.

Hi - sorry for the late response.
Looks good to me, and the breaking change makes sense. I'm probably the wrong person to evaluate the code itself though :)
Happy to see this expanded on - thanks @GP8x!
