Add cljstyle 0.12.1

[robhanlon22]

cljstyle is a tool for formatting Clojure code.

After making all changes to the cask:

• brew cask audit --download cljstyle is error-free.
• brew cask style --fix cljstyle reports no offenses.
• The commit message includes the cask’s name and version.
• The submission is for a stable version or documented exception.

Additionally, if adding a new cask:

• Named the cask according to the token reference.
• brew cask install cljstyle worked successfully.
• brew cask uninstall cljstyle worked successfully.
• Checked there are no open pull requests for the same cask.
• Checked the cask was not already refused.
• Checked the cask is submitted to the correct repo.

Resolves greglook/cljstyle#36.

Thank you, and welcome.

From faq/rejected_casks:

The app is both open-source and CLI-only (i.e. it only uses the binary artifact). In that case, and in the spirit of deduplication, submit it first to Homebrew/core as a formula that builds from source. If it is rejected, you may then try again as a cask (link us to the issue so we can see the discussion and reasoning for rejection).

Hi @vitorgalvao—I looked into building this from source, but it has a build-time dependency on GraalVM, which is cask-only: https://github.com/graalvm/homebrew-tap Any suggestions on where to go from here? Thanks.
