🐛 Dataset file locked during lifetime of script

[jsnel]

Describe the bug

A minor issue when reading in / loading data from nc file. When doing so the files are locked throughout the runtime of the script.

Solution

Instead of

@register_data_io("nc")
class NetCDFDataIo(DataIoInterface):
    def load_dataset(self, file_name: str) -> xr.Dataset | xr.DataArray:
        return xr.open_dataset(file_name)

One can instead use:

@register_data_io("nc")
class NetCDFDataIo(DataIoInterface):
    def load_dataset(self, file_name: str) -> xr.Dataset | xr.DataArray:
        with xr.open_dataset(file_name) as ds:
            return ds.load()

which avoids file locking.
