AttributeError in make_feeds worker

After updating numpy in nowcast-env on skookum from 1.22.3 to 1.24.0:

numpy.asscalar() was deprecated in numpy=1.16 and removed in numpy=1.23. numpy.ndarray.item() is the replacement method to use.

The traceback above leads to instances of numpy.asscalar() in SalishSeaTools. Those were fixed in SalishSeaCast/tools#71. There are also instances in make_feeds._calc_wind_4h_avg() which are fixed here.
