New lens/features holding pen

The following are roughy in order of my interest level

• https://hackage.haskell.org/package/xlsx-0.7.2/docs/Codec-Xlsx-Lens.html

• https://hackage.haskell.org/package/giphy-api-0.6.0.1/docs/Web-Giphy.html could be good for demoing traverseOf

• https://hackage.haskell.org/package/units

• https://hackage.haskell.org/package/sv

• https://hackage.haskell.org/package/cabal-lenses

• https://hackage.haskell.org/package/colors

• https://hackage.haskell.org/package/accelerate might be neat to show load data and doing a fast computation all within refactorio

• https://hackage.haskell.org/package/versions

  I would love to get something like versions working but I had trouble getting new versions to build without causing conflicts with megaparsec and I had trouble getting anything useful out of older versions of versions (lol).

Random thoughts:

• Maybe find a way to make duckling useful from refactorio
• Maybe find a way to allow for ad-hoc unit tests of data eg. you write a test (Hspec? quickcheck? other?) in terms of a ByteString and have it validated against the ByteString of each file.

https://hackage.haskell.org/package/imagemagick or similar... would need to design the lenses but could be super cool.
