Hide cameras and badges if respective entities = 0

[GitHubGoody]

Is your feature request related to a problem? Please describe.
I like the USPS and Amazon cameras, but until and unless their respective sensors are greater than 0, I'd prefer them to be hidden rather than the placeholder image(s). This would save otherwise wasted space on the display.

It would also be great if the badges could also be hidden if their entity value = 0. This would save time scanning all of the icons.

Describe the solution you'd like

If the USPS or Amazon sensor entities = 0, I'd like the option to hide their respective camera(s).

I'd also like icons to be hidden if their respective value = 0.

Describe alternatives you've considered
None

Would love this too.

Wonder if it can be solved with card-mod? Like this: #42 (comment)
