Add missing dependencies in victory-histogram

[Mike-Dax]

https://github.com/FormidableLabs/victory/blob/master/packages/victory-histogram/src/helper-methods.js

Requires both d3-scale and react-fast-compare without including them in the package.json.

This works by coincidence in some codebases but will fail in any using Yarn v2.

This has happened a couple of times before:

#1478
#1496
#1570

I would recommend adding a test to your CI that installs and runs some tests of the package using Yarn v2 to catch these errors before release, given these patch / minor changes break downstream dependencies.

@Mike-Dax Thanks for this PR! react-fast-compare and d3-scale are both dependencies of victory-core, which victory-histogram depends on, making it particularly unlikely for us to catch this issue. I'll update our CI setup as you recommend.
