Image saturate / desaturate appear on the doc, but not on the module...

[mlbonniec]

Expected Behavior

Hi, I would like to reduce or increase my image saturation, as specified in the doc here, but the module doesn't have those options.
My issue refer to another one, previously closed: #968

Current Behavior

Type '"saturate"' is not assignable to type 'ColorActionName'. because saturate or desaturate (and lighten, darken) doesn't exist on ColorActionName.

Failure Information (for bugs)

---

Steps to Reproduce

Try to change the saturation of an image

image.color([{ apply: 'saturate', params: [10] }]);

As you can see on the screen, even Intellisense doesn't propose me saturate, desaturate...

Any update on this? Having same issue.
I checked the code and colorActionName is not defined for lot of things like saturate, desaturate,grayscale etc.

Could you make a PR to update the types?

[daniellwdb]

Could we make this an enum and export it so it makes refactoring easier?
