Add ligature for |> (Elixir pipe operator).

[DevotionGeo]

I used the font, it looks awesome, but the only problem is that I am used to the |> (pipe operator's) ligature using Fira Code and Operator Mono (both of the fonts have ligature for pipe operator).
After Elixir, ELM also adopted pipe operator and it's also coming to JavaScript and soon may also come to Erlang. So we'll see more of pipe operator in the near future.

Following example uses Fira Code.

Thank you for designing this beautiful font!
