fix(contrast-colors): Add d3 as dependency

[joestrouth1]

Description

Fixes #24

Package depended on d3 without declaring so.

To-do list

• I have read the CONTRIBUTING document.

• This pull request is ready to merge.

Should be OK to merge unless you'd prefer it be a peer dep so folks can bring their own version.

Aside:

When cloning this repo and running lerna bootstrap, it failed with the following error:

error Couldn't find any versions for "@adobe/leonardo-contrast-colors" that matches "^0.1.0"

I think this will fix itself once it's not tagged as prerelease, but as someone not super familiar with lerna it was a bit of a barrier. Wound up changing the package.json version to 0.1.0, bootstrapping, then changing back after adding d3.

@joestrouth1 good catch! Note that we don't use lerna bootstrap, instead just run yarn install since we use yarn workspaces.

I don't think it needs to be a peer dependency, so this is good to go. Thank you!

Released @adobe/[email protected] with the corrected dep. Thanks!

Also, that issue on bootstrap was due to referring to the wrong version in the ui package. I just pushed a commit that fixes that.
