Add compress_attributes.js transform

To trim attr descriptions.

After thinking about this some more, maybe plotly.js should compress its attributes by default. That is, we should list the compress attribute transform in its package.json.

At the time of the first plotly.js FOSS release, I wasn't aware of the --ignore-transform=MODULE browserify option. I'm thinking by default we should 🔪 the attribute descriptions by default and allow users to optionally include them in custom builds. Thoughts?

Strong agreement. Was wondering about this as I realized my custom bundles are giant because I'm not bothering to pull in that transform.

Strong agreement.

Awesome. I'll put that on my todo list. Feel free to close this issue 👍

No prob. Are you able to close the issue? I can, but curious if non-org-owner push permissions (there is no org) include managing other functions.

... I think so.
