Issue: String coordinates in netcdf datasets https://github.com/ecmwf/earthkit-data/blob/fe88303a00cc3dcbb2890f3dab1ebbb13a9d5c15/earthkit/data/readers/netcdf.py#L36 I'm trying to read a netcdf dataset with string coordinates. The netcdf field is a list of points, each point has an ID (for instance G0001) and a time series, so two dimensions: station and time. I get the following error when trying to read with earthkit: ``` File /etc/ecmwf/nfs/dh1_home_a/macw/git/test/hat/venv/hat/lib/python3.10/site-packages/earthkit/data/readers/netcdf.py:37, in as_level(self, level) 36 def as_level(self, level):

Files to edit

earthkit/data/readers/netcdf.py

Approach: Modify as_level method to avoid converting non-numeric levels to floats.
