v2.0.0: gobalt version 2 is live!

Hello! It's been quite some time, huh?
Today, cobalt has updated it's API, and we have updated the library too! Here's what changed (a lot, breaking changes even)

Additions:

• Proxy (bool): Now Cobalt can proxy files for you, default is false;
• AudioBitrate (int): You can changed audio bitrate downloaded from cobalt;
• Mode (downloadMode): Now you don't need to set AudioOnly or VideOnly to download only the audio or video. Either Auto, Audio or Mute;
• File name is now returned from the api directly.

Changes:

• Default API url is https://beta.cobalt.canine.tools has there no public official instance api anymore;
• Youtube dubbed audio language is now on Settings struct;
• Renamed AudioFormat, FilenameStyle, TikTokFullAudio, TwitterConvertGif, VideoQuality, YoutubeDubbedAudio, YoutubeDubbedLanguage and YoutubeDubbedLanguage.
• You can use your own http.Client now.

Default settings

New default options:

• Url: "" (empty);
• YoutubeVideoFormat: H264;

• AudioFormat: Best;
• AudioBitrate: 128;
• FilenameStyle: Basic;

Run()

Now it only checks if the url was set or not.;
If it fails it will return the cobalt.error.code;

Updated a lot of things, now it returns only v10.0.0 or higher cobalt instances, supported services, score (benchmark), protocol and trust
