Add bashu contributions

This PR adds @bashu’s latest submissions (https://github.com/caskroom/homebrew-cask/pull/8006 and https://github.com/caskroom/homebrew-cask/pull/8010), with a few minor modifications. Hope you don’t mind, @bashu; I’m adding them now so we can close the PRs on the other side.

@rolandwalker @ndr-qef Technically the license for these should be `:commercial`. However, it appears that although they still require a license, the developer just outright gives you one to input, for free. It is then both technically `:gratis` and `:commercial`, so `:closed` seems appropriate.
