Previously, mpycert.der was the Intermediate certificate which is regularly re-issued by Letsencrypt. Also changes ssl_cert.py to load the cert data from the same file as test_sslcontext_client.py, so the DER string doesn't have to be pasted into the source. This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>
