- retro-compatible change: keep using host/owner if set
- otherwise extract owner and eTLD+1 from domain field
- documentation updated to only use the `domain` field
- Only calls DNS API(s) once the public IP address changes
- Only one ip method per ip version (ipv4, ipv6, ipv4/v6)

- Support to update ipv4 and ipv6 records separately, for supported DNS providers
- Move from settings in environment variables `RECORDi` to a configuration file *config.json*
- Each entry can has its own delay optionally
- Proper cleanup on exit (close channels etc.)
- Fan out channels architecture for force and quit channels to all updates goroutines
- Each entry has its own set of fields explained in the readme
- Retrocompatibility for environment variables entries for now
