pmlmodelling/nctoolkit: v0.4.6

This release enhances existing methods, with a focus on improving subsetting.

The select method is replaced by subset. This behaves in the way same way as select, but will also allow users to subset data based on longitude and latitude using lon and lat as args. select is now deprecated.

The export methods to_nc, to_xarray and to_dataframe now allow only a subset of the data to be exported. Additional arguments can be sent to the methods, and they will then be sent to the subset method.

The new matchpoint methods for matching netCDF and point data have been smoothed out with additional options.

Minor bug fix: The weights in datasets with recycled regridding weights were not copied properly. This is now fixed.
