Extended mappings

[d-miketa]

Hi, and thanks for this plugin! I'm just trying out Emacs, having used Neovim for a while, and couldn't imagine the transition without a commentary-like plugin. :)

Recently, Comment.nvim introduced a couple extra mappings that I've found extremely ergonomic and useful, especially the following:

`gco` - Insert comment to the next line and enters INSERT mode
`gcO` - Insert comment to the previous line and enters INSERT mode
`gcA` - Insert comment to end of the current line and enters INSERT mode

Is this something you'd be interesting in adding to evil-commentary, possibly via a PR? You've mentioned preference for simplicity on another issue, but tbh once you get used to gco it's tough going back!

Hi @d-miketa, thank for suggestion, I do prefer simplicity. I don't however object to a fork with the same name or -extra. We can also mention your work in README.
