Expose more SenseableBase properties.

Refactored get_trend() to handle more than two keys from self._trend_data.

• 'key' is now a keyword argument on get_trend() with a default of "consumption", no longer is set as a boolean inside the function.
• Perform type check on data referenced by key, ensure type is ...
• dict (for consumption/production)
• float (for to/from_grid and net_production properties)
• int (for production_pct).
• Converted existing True/False parameters on self.get_trend() calls to explicit key names.

Added new properties exposing existing information already in self._trend_data for daily scale and above.

• production_pct
• net_production
• from_grid
• to_grid
