net/geoipupdate: Update to 7.0.1

• BREAKING CHANGE: Improvements to the HTTP download API.
• The client now calls two new endpoints:
  • /geoip/updates/metadata which is responsible for getting information about a database edition.
  • /geoip/databases/{edition-id}/download which is responsible for downloading the content of a database edition. This new endpoint redirects downloads to R2 presigned URLs, so systems running geoipupdate need to be able to reach
  • mm-prod-geoip-databases.a2649acb697e2c09b632799562c076f2.r2.cloudflarestorage.com in addition to updates.maxmind.com.
• BREAKING CHANGE: The public package API has been redesigned. The previous API was not easy to use and had become a maintenance burden. We now expose a Client at github.com/maxmind/geoipupdate/client with a Download() method. The intention is to expose less of the geoipupdate internals and provide a simpler and easier to use package. Many previously exposed methods and types are now either internal only or have been removed.
• BREAKING CHANGE: If set, GEOIPUPDATE_VERBOSE must either be 0 or 1. All other values will return an error.
• Setting GEOIPUPDATE_VERBOSE to 1 now works as expected. In the 6.0.0 and 6.1.0 releases, the flag was ignored. Reported by pmcevoy. GitHub #298. geoipupdate now supports retrying on more types of errors such as HTTP2 INTERNAL_ERROR.
• Now geoipupdate doesn't requires the user to specify the config file even if all the other arguments are set via the environment variables. Reported by jsf84ksnf. GitHub #284.
