feat(Kids): Add blockChannel command to easily block channels

[rsandbach]

Added new command and classes to support the Report / Block channel for kids

Small change to ToggleButton to allow parsing when there is now defaultIcon defined.

[rsandbach]

This would be a start to #422.

Probably better to put the kids only block channel in src/core/clients/Kids.ts instead of the interaction manager, as they presumably can't be used for YouTube or YouTube Music?

Please place your new kids only parser classes in the src/parser/classes/ytkids instead of src/parser/classes/channels.

[rsandbach]

I went back and forth on this. My initial implementation was under Kids, but these particular actions/UI elements are only available within the YouTube web client when logged into an account that curates content for supervised accounts/kids profiles.

Just skimming through the code and it looks good. Will do a proper review tomorrow or Tuesday.

Edit:
Done! :)

This is nothing to do with ytkids. This is for supervised child accounts that are set to 'Explore', giving them access to yt proper.
