Fixed problem with netatmo wind guages.

Hi,

Thanks for a great plugin, that will solve some of the things I want to do on a project. I have access to a rain module and a wind module. The code you provided for the rain module seems to be working perfectly, however I had to fix the code for the wind module.

2 things:

1. The information regarding what is present in the wind module is not the same as in the other modules. The information regarding datatype is just "Wind". There are no such DashboardData, so I checked for the module and added the correct values.
2. In the DashboardData struct, you had a variable called GustStrengthfloat32, which seemed just to be an error. I fixed that as well.

Again, thanks for the work you already put in. By patching this I was able to use it perfectly!
