Move onewire raw_value attribute to separate sensor

[epenet]

Breaking change

The raw_value state attribute has been removed from all onewire entities.
Please use the corresponding sensor instead.

Proposed change

The raw_value state attribute has been removed from all onewire entities.
In the case of temperature, pressure, illuminance and humidity sensors, this has been moved to a separate sensor.
For the other sensors (voltage, count, moisture) the automatic rounding has been removed

Hey there @garbled1, mind taking a look at this pull request as it has been labeled with an integration (onewire) you are listed as a code owner for? Thanks!

Could this be included in 2021.12.0 ?

I worry that this will break a certain class of automation. We don't know if users are using this in automations anywhere. While the temperature of my back yard is not useful at 3 decimal places, the temperature of my aquarium, or anything I'm attempting to temperature control, absolutely is. Or if I'm using a pair of sensors to measure a minor difference between two things, such as pressure sensors on either side of an AC filter to measure the filter dirt.

I fully get that alot of people probably use these to just measure a few room temperatures here and there, and that is the sort of default case, but I'd hate to break anyone doing anything more advanced.

As discussed on Discord, I will use an option flow instead to deactivate the state attribute.

Another option would to be to make the raw value its own sensor and disable it by default

Don't clone the raw value of a moisture device, they are identical.

same with 0-3, and the leaf wetness too.

Keeping as draft until #63222 is resolved

[epenet]

Note: I have opened an arch discussion to see if there are other ways to solve this: home-assistant/architecture#713

[epenet]

#63222 is now merged - but I think #64315 is still needed

Not stale

Giving up on this - probably not really needed.
