Feature: Definition types

[piotr-cz]

Fixes #18

[piotr-cz]

Testing instructions:

npm uninstall react-number-easing
npm install "github:piotr-cz/react-number-easing#feature/definition-types"

[piotr-cz]

I didn't success with referencing types from the @types/eases - it didn't show easing types in VSCode when using this package in another project so I hardcoded them.

@javierbyte @adjohu @migreva I love this project and I really want to use this on my TypeScript application. Is there any progress about adding types?
