wait_till_presnese: Name is weird and should have verbose=False

[gyger]

I think the Name is a spelling mistake and it would be nice to have a verbose parameter for this function.

Thanks. But I think the name is still weird after correcting the typo. Users can't guess what it is doing from its name.

Could you maybe suggest a better name?

In commit c7978, I changed the name from wait_till_presence to wait_for_data. I also corrected a typo in a variable name inside the function.
Still has to be tested.

I think it is better. We also need to update the documentation before close the issue.

We were also considering await instead of wait_for, but await typically returns data already. I updated the documentation with the new name and the verbose argument.

tested, it works.
