* fix(pkg.go.dev): import a subpackage containing the assets We're trying to fix this issue that pkg.go.dev does not build. Thanks to @hellais for this very neat idea! Let's keep our fingers crossed and see whether it fixes! * feat: use embedded geoip databases Closes https://github.com/ooni/probe/issues/1372. Work done as part of https://github.com/ooni/probe/issues/1369. * fix(assetsx): add tests * feat: simplify and just vendor uncompressed DBs * remove tests that seems not necessary anymore * fix: run go mod tidy * Address https://github.com/ooni/probe-cli/pull/260/files#r605181364 * rewrite a test in a better way * fix: gently cleanup the legacy assetsdir Do not remove the whole directory with brute force. Just zap the files whose name we know. Then attempt to delete the legacy directory as well. If not empty, just fail. This is fine because it means the user has stored other files inside the directory. * fix: create .miniooni if missing
