feat(proto): Add comment_id to commentSectionParams

[gurumnyang]

Fixes #689

The proto.encodeCommentSectionParams method now has a new optional parameter called comment_id, which allows highlighting a specific comment when the page is opened. Here is an example code snippet:

//continuation for /watch?v=jlAd027IBsc&lc=Ugxvmarhks-D40zwQKJ4AaABAg
const continuation = encodeCommentsSectionParams(
  "jlAd027IBsc",
  {
    comment_id: "Ugxvmarhks-D40zwQKJ4AaABAg"
  }
);
console.log(continuation);

The output of the above code will be:

Eg0SC2psQWQwMjdJQnNjGAYyQiIuIgtqbEFkMDI3SUJzYzAAeAKCARpVZ3h2bWFyaGtzLUQ0MHp3UUtKNEFhQUJBZ0IQY29tbWVudHMtc2VjdGlvbg%3D%3D

Process finished with exit code 0
