What?

This PR removes Lodash's _.map() from the blocks package. There are just a couple of usages and conversion is pretty straightforward.

Why?

Lodash is known to unnecessarily inflate the bundle size of packages, and in most cases, it can be replaced with native language functionality. See these for more information and rationale:

How?

We're using Array.prototype.map() instead.

Testing Instructions
