add customization options for weather card

[Seamus-Mccartin]

The home assistant weather entity currently supports multiple forecast attributes but there is no way to customize which attributes are displayed in the weather card. By default, the weather card displays attributes for condition and temperature(high) with the optional temperature(low).

Supported attributes are taken from the documentation

Name	Type	Default	Description
datetime	string	Required	UTC Date time in RFC 3339 format.
temperature	float	Required	The higher temperature in °C or °F
condition	string	None	The weather condition at this point.
templow	float	None	The lower daily Temperature in °C or °F
precipitation	float	None	The precipitation amount in mm or inch.
precipitation_probability	int	None	The probability of precipitation in %.
pressure	float	None	The air pressure in hPa or inHg.
wind_bearing	float or string	None	The wind bearing in azimuth angle (degrees) or 1-3 letter cardinal direction.
wind_speed	int	None	The wind speed in km/h or mi/h.

Suggested feature additions

Add options to modify the formatting of and attributes displayed in the forecast

• time-mode: hourly|daily
• forecasts: int
  controls how many hour-period/day blocks the forecast displays
• hour-period or interval: int
  used when time-mode is set to hourly. Controls how many hours each forecast block covers
• forcast-attributes:
  • templow: bool
  • precipitation: bool
  • precipitation_probability: bool
  • pressure: bool
  • wind_bearing: bool
  • wind_speed: bool
• units:
• • pressure: inHg|mmHg|kPa|hPa|bar|atm

The default behavior should be maintained ie: auto-formatting day/hour based on weather entity data and using state high and low temperatures for the forecast. Units should default to system defaults but it might be useful to allow overrides on the card.

this would be a useful way to display info from the weather template integration.
