chore(updater): incorporate `FetchServers` method in `Provider` interface - Each provider interface can now fetch updated servers data - Rename each provider updater subpackage name to `updater` - Updater constructor does not take a settings struct - Updater update method takes in a slice of provider strings 2022-06-09 23:47:12 +00:00			`package updater`
Maintenance: refactor servers updater code - Require at least 80% of number of servers now to pass - Each provider is in its own package with a common structure - Unzip package with unzipper interface - Openvpn package with extraction and download functions 2021-05-08 00:59:42 +00:00
