fix(Channel)!: Remove getChannels() and has_channels, as YouTube …

…removed the tab (#542)

BREAKING CHANGE: YouTube removed the "Channels" tab on channels, so this
pull request removes the `getChannels()` method and `has_channels`
getter from the `YT.Channel` class, as they are no longer useful. The
featured channels are now shown on the channel home tab. To get them
you can use the `channels` getter on the home tab of the channel.
Please note that some channel owners might not have added that section
to their home page yet, so you won't be able to get the featured
channels for those channels. The home tab is the default tab that is
returned when you call `InnerTube#getChannel()`, you can also access
that tab by calling `getHome()` on a `YT.Channel` object.
