Support importing individual methods?

[owenoak]

One of the things I like about lodash is the ability to pull in individual methods rather than the whole lodash toolchain via:
`import isEqual from "lodash/isEqual"

For your project, the instructions state that you should _.mixin(...) to add inflector methods to lodash, but I never use lodash that way.

I quickly found that I could do:
import inflection from "lodash-inflection"
export const singularize = inflection.singularize.bind(inflection)
and it seems to be working fine.

So, my request is to add support to importing individual methods in a style similar to lodash, so:

import singularize from "lodash-inflection/singularize"
etc.

Hi, I am not against this but I do not have time to do this now.
If you want to create a PR for this I will be more than happy to merge.
Thank you!
