This update brings the new method for fetching GCP ip ranges from their published json file instead of the janky dns crawling mechanism.
It also brings a new flag, `--compacted` which can be used to automatically compact neighboring CIDR ranges. When run against the four cloud providers that sephiroth supports, a reduction in size of roughly 10x is seen.
bash
sephiroth -t aws -t gcp -t oci -t azure -s nginx --compacted >/dev/null
sephiroth -t aws -t gcp -t oci -t azure -s nginx >/dev/null
