Main sensor still in text format

[DominiqueRT]

Pollens home assistant : v2022.02.02

Even if sensor if configurated in numeric, the main sensor for the region remains in text format.

eg : sensor.pollens_14 = faible instead of 1

Its not a bug. The main sensor is left in the original form (like in the first version). Maybe a new numeric sensor in fire release.

Add a new sensor with "_num" for numeric level value ex: sensor.pollens_14_num
