Update or create a dns record through the DigitalOcean API.
This script makes the assumption that there is only one FQDN that matches a given combination of name and record type. So if you have two A records for foo.example.com, this script might fail or delete one of them, depending on what I have implemented at that moment.
Right now it simply sets all records that the DO API returned for the given combination to the given --data.
I might even try to fix this shortcoming in the future.
Multiple --type arguments with their own address each for updating A and AAAA in one go would also be nice.
It also exposes your DO API token in the process list while running. You have to trust your local machine.
