Associate .chn with chaiNNer on MacOS (chaiNNer-org#2115)

associate .chn with chaiNNer on macOS

- added association of .chn filetype with chainner on macOS
- added file type icon
- added open-file event for macOS

This addresses chaiNNer-org#1062 but does not solve it completely, since file association only works on macOS ATM.
