Replace overheated with the three new fields for plugs

[padenot]

This should fix #248 while ensuring older devices keep working if the library is updated but not the firmare of the device.

I only have P110 and P115, but updated all other devices -- those are untested but it should be harmless if it hasn't been renamed there.

[padenot]

The field has changed from a bool to a string, and we should probably map to an enum, but I don't know of the possible variants just yet, so I've left it as a bool. We can fix this later, this fixes the library.

Also it's unclear to me if we want to align the python API, how to make an alias, etc.

It would be best to update the plugs only for now and have the field called overheat_status with a non-optional enum.
I've left a comment on #248 with the enum values.

If you're happy to make the Rust changes, I can do the Python ones afterwards.

Updated. For some reason the up-to-date p110 and p115 don't have this overheated field right now so I left it as optional.

Thank you for this.
I’ve reviewed it and made some adjustments that I believe are appropriate, so that it can be released today.
