Accept license and gdpr by command

[Derek-K]

@ThomasWilla , I aware of those options. However, for legal reasons, the end-users should accept the license agreement by Ookla before using their binary.

I purposely left out those options is to make sure the end-user will have the option to read and accept the license agreement on their first run, therefore I opt'ed out including them.

Once the end-user accepted the license agreement, those options no longer needed.
