error pyet.jensen_haise using method=1

[bombilator]

Describe the bug
Calling pyet.jensen_haise() with method=1 gives TypeError: extraterrestrial_r() takes 2 positional arguments but 3 were given.

To Reproduce
Steps to reproduce the behavior:

1. Call pyet.jensen_haise(), provide necessary variables tmean and lat, with method=1
2. run the code
3. See TypeError: extraterrestrial_r() takes 2 positional arguments but 3 were given

Expected behavior
Get a pandas.Series or xarray.DataArray containing the calculated potential evapotranspiration [mm d-1]

Screenshots
From file radiation.py:

Additional context
In file radiation.py on line 107, an additional variable is given in the function extraterrestrial_r() like so; extraterrestrial_r(index, lat, tmean). The variable tmean should be removed for the method to work properly.

Thanks for reporting this @bombilator (Nice to see you here btw ;-))!

I'll implement the fix later this week, but feel free to open a PR if you need it earlier or have the fix already.

Cheers,

You too :) Perfect. I have to prioritise other things right now, but I'll check for updates when I get back to it!

Cheers,
