[Feature] Add support for icons

[N1c093]

Hello,

it would be great, when the display also support mdi icons.
This would save some space for letters on the display.

Thank you

I'm planning to add icons soon. But I can only fit ~1400 icons on the device, not the whole mdi set.

I was thinking of adding the 646 icons in the Home Automation category at first. Do you think that's sufficient or should I add another category?

This is a really good start in any case.
I thought the small arrow category would be useful too.

@nplan this sounds like a good start 👍

I would also agree with @hilsonp that some arrows would be helpful.

Rather that storing icons on the device, wouldn't it be possible to send icons on the fly to the device when they are in use, over mqtt maybe ? I'm not very familiar with home assistant API but I assume there is a way to replace the label field by an "image" field or something similar.

@mcarbonne it could be done, but would require a custom integration in HA. Which would add additional setup steps. Also, the users who use device without HA (although I doubt there's many) would not be able to use the feature.

MDI added in v2.1.0.
