Glance card: per-entity option to invert state color

[rigrig]

I expect some of my devices to be active by default, so it would be nice if their icons could be highlighted when the exception occurs.

Example: This card

type: glance
entities:
  - entity: binary_sensor.all_windows
  - entity: switch.transmission_switch
  - entity: cover.all_screens

Looks like this:

• The window sensor is highlighted, because some windows are open: this is what I want
• The Transmission switch is on, but I leave it on almost all of the time, so it would be nice to highlight it when I turned it off instead.
• The cover sensor is highlighted, because all sunscreens are raised (for covers "open" = "active"), but I would like it to be highlighted when the screens are closed instead.

A per-entity invert_state_color: true option would be nice, even nicer would be if you could override state_color per entity, and besides true and false, 'invert' was also an option:

type: glance
entities:
  - entity: binary_sensor.all_windows
  - entity: switch.transmission_switch
    state_color: 'invert'
  - entity: cover.all_screens
    state_color: 'invert'

would have the same effect as

type: glance
state_color: 'invert'
entities:
  - entity: binary_sensor.all_windows
    state_color: true
  - entity: switch.transmission_switch
  - entity: cover.all_screens
