Sensors interface

I skipped all the changes to versions of package.json, I did it only in the py file
not sure if I missed anything

Used this as reference 5d87a1b

Probably the single sensor could contain some metadata, i.e. unit or any descriptor of the utility, instead of plain strings

Something like
sensors: Record<string, {name?: string, value?: any, data?: any}>;

name is required? what names are you using?

For homeassistant, the id would be the entity_id, which could be pragmatic, friendly_name can give a bit of context. Most of the times entity IDs are autogenerated and not comprehensible
