Is this a BUG REPORT or FEATURE REQUEST? (choose one): Feature Request

I've switched to tcomment over vim-commentary for a few different reasons:

1. Commenting in JSX (this is actually already implemented in VSCodeVim, it doesn't work very well in the original vim-commentary implementation)
2. More flexible commenting with movements and text objects.

Consider the following:

function foo(bar: string): string {
  return 'bar';
}

If I have my cursor on the b of bar and press gci(, vim-commentary will produce the following:

//function foo(bar: string): string {
  return 'bar';
}

tcomment, on the other hand, will produce the following:

function foo(/*bar: string*/): string {
  return 'bar';
}

VSCodeVim currently implements the vim-commentary functionality, I would argue that the tcomment functionality is much better.

Start by locating the existing VSCodeVim implementation of vim-commentary behavior and its text-object handling, then compare it with tcomment's documented behavior. Verify the change against the examples in the issue, including gci( producing an inline comment around the selected text, while preserving existing JSX commenting behavior.
