Support for Grocy 3.x api

[isabellaalstrom]

There are a lot of changes in the 3.x version. Some things seems to have broken.

Hey! Do you know what things are broken? It seems like the chores are still working, so stock and products?

[isabellaalstrom]

Stock seems to work, but I would say products have issues.
See this: custom-components/grocy#114

Edit: Yeah, my stock-sensor is working correctly, so it seems to be the binary sensors.

@isabellaalstrom i published a new release v0.25.0 which made the lib compatible to grocy 3.0.0+ as far as I know, could you check it out maybe?
Also it might make sense to add some sort of information text about the "new" incompability with grocy < 3.0.0 to the integration.

[isabellaalstrom]

Yeah! I will look at this tomorrow. 👌

Updated to 0.26.0 in my local env and now I get this error. I don't use barcodes, and it seems it expects them? Nothing is updating as it is now.

@isabellaalstrom I (hopefully) fixed your issue and another one in a new 0.27.0 version :)

[isabellaalstrom]

Will check at once!

[isabellaalstrom]

All sensors and binary sensors are now working! 🎉
