What's the problem this PR addresses?

How did you fix it?

Added lodash as a dependency

@alexiscordova, @fredboyle, and @zahnster were recent contributors to this repository. Can one of you look at this issue?

[alexiscordova]

@iclanton none of the folks you listed work at Salesforce anymore. @Dottenpixel might be your best bet

Cheers @alexiscordova!

@merceyz, thank you for your contribution. We usually have a bot that prompts contributors to sign a contributor's licensing agreement (CLA) before accepting their PRs. I've just enabled the bot on this repo.

We can make the change internally, or if you'd like recreate this PR and sign the CLA when prompted by the bot.

I've already signed the CLA, ref salesforce-ux/scss-parser#43 (comment).
