Add SetRequired and SetOptional types

[crhistianramirez]

Now that I'm looking at it maybe SomeRequired and SomeOptional would be better names? Couples the two, as it should and expresses intent pretty well.

Edit: changed to SetRequired and SetOptional per feedback from sindresorhus

maybe SomeRequired and SomeOptional would be better names?

👍 Some other name ideas: SetRequired, MakeRequired, RequiredKeys. One problem with SomeRequired is that it might give the impression to the user that it also makes unspecified keys not required (optional).

It's really too bad that the built-in Required type is not named RequiredAll or AllRequired...

You need to add the types to the readme.

@sindresorhus thank you for the feedback I went ahead and resolved each line item. I'd appreciate additional feeedback you might have :)

Also did you prefer that I squash all the commits to clean it up? Wasn't sure, the readme didn't mention it.

Looks good now. Thanks :)
