Duplication of types included in the standard library

[chocolateboy]

The idea is that these types will hopefully make their way into the language proper, at which point you can simply stop importing them from type-zoo and be on your merry way.

Some of the types implemented here have been implemented in TypeScript's standard library, e.g.:

• Parameters (v3.1)
• Omit (v3.5, announcement)

Since the versions implemented here are redundant, and in some cases more limited, I would suggest either aliasing them to the stdlib version, or documenting the supported TypeScript version and removing them.
