Pick one: Lodash or Ramda and import modularly

[ChristopherChudzicki]

Since this project is being used in OCW we are interested in trimming its size.

Currently, all of lodash is being included in OCW because of its dependency here. (Admittedly, that's arguably a treeshaking issue on OCW's side). Additionally, this project is including both lodash and ramda which overlap heavily. So let's pick one.

Acceptance Criteria

• do not include both lodash and ramda
• use modular imports ("lodash/cloneDeep" or "ramda/src/whatever" rather than including the whole library
