Expose the location name as state when daily info status is 7

[EnJens]

The 7 status indicates a physical placement is set. This appears to be potentially unique per school/institution, but the id and name is included in the getDailyOverview response.

It's not entirely clear if this is available in other statuses, so I've kept it to safe for now. It could probably be simplified to just checking if location is not None.
I realize these are available as attributes on the sensor, but getting it as the state makes it easier to display and you get a better history.

I've captured two responses from my kids school with the relevant snippets below:

status: 7
location:
  id: XXXX
  name: Ude
  description: ""
  symbol: icon-Aula_sfo_slide
  startTime: null
  endTime: null
  startDate: null
  endDate: null
  isDeactivated: false
  weekDayMask: null
  isDateIntervalsEnabled: false
  isTimeIntervalsEnabled: false
  isWeekdaysEnabled: false


status: 7
location:
  id: XXXX
  name: Hal
  description: ""
  symbol: icon-Aula_sfo_gymnastic_hall
  startTime: null
  endTime: null
  startDate: null
  endDate: null
  isDeactivated: false
  weekDayMask: null
  isDateIntervalsEnabled: false
  isTimeIntervalsEnabled: false
  isWeekdaysEnabled: false
