v1.2.0beta

Added a column to extract the DMARC Policy to make it easier to find p=none / p=quarantine / p=reject.

Also started work to check domain e-mail policies against requirements published by service providers.

E.g. bulk email requirements by Microsoft which I understand to be
# SPF + DKIM + DMARC required
# DMARC policy: p=none (or better), strict SPF (aspf=s) and/or DKIM (adkim=s) alignment
