Change the name of the sensor created by the last.fm integration

Hello,

I would like to request a change to the sensors that are created by the last.fm integration.
At the moment, the sensor name is just your user name ( sensor.yamifrankc , for example)
which could cause some confusion, specially if you have other sensors that might have that username on their name.

I think the best would be to make it more descriptive, “lastfm_username”, for example.

Thanks
