The cookiecutter template creates import functions with wrong prefix

[ladc]

The functions are importer_blabla but the pysteps code looks for import_blabla to include in the importers module. Could someone confirm that this is not consistent or are we doing something wrong here?

We fixed this in the new version of the cookiecutter, and merged the changes in main (see #6 ) .
We still need to merge the changes to the main pysteps repo to be consistent with the new cookiecutter. This concerns mainly the io.interface and postprocessing.interface files.
