Allow int amp values for charging speeds other than reduced and maximum

Is your feature request related to a problem? Please describe.

Hi I’ve a skoda citigo and I would like to select charging speed that I want but I’ve saw that currently it allow only “maximum” and “reduced” string values which map to 254 and 252, it would be nice to allaow also to take directly int values, infact I’ve tested by changing the code and if you pass a value from 5 to 32 (for skoda citigo) to the api it set directly the current to the correspond value

Describe the solution you’d like

Somethig like that:

    async def set_current(call):
        """Prepare data and modify for data call."""
        try:
            current = call.data.get('current')
            if current == "maximum":
                current = 254
            elif current == "reduced":
                current = 252
            _LOGGER.debug("Try to fetch object for VIN: %s" % call.data.get("vin", ""))
            vin = call.data.get("vin")
            car = connection.vehicle(vin)
            _LOGGER.debug(f"Found car: {car.nickname}")
            _LOGGER.debug(f"Set charger current to {call.data.get('current')} ({current})")
            await car.set_charger_current(current)
            async_dispatcher_send(hass, SIGNAL_STATE_UPDATED)
            return
        except Exception as error:
            _LOGGER.warning(f"Couldn't execute, error: {error}")
            async_dispatcher_send(hass, SIGNAL_STATE_UPDATED)
        raise Exception(f"Service call failed")    

SERVICE_SET_MAX_CURRENT_SCHEMA = vol.Schema(
    {
        vol.Required("vin"): cv.string,
        vol.Required("current"): vol.Any(vol.In(range(5, 33)), vol.In([ "maximum", "reduced"])),
    }
)

I have tested and verified that integer values from 1 to 16 works for my Superb iV, it also correctly limits the maximum charging current to the correct value. For instance 8 ampere instead of being limited to reduced (6) and maximum (16). This will be integrated in upcoming release 1.0.43-RC3
