Add an `omit` option to skip some fields in the output object

[kilianc]

This may be out of scope but I find myself doing camelcaseKeys((omit(o, 'foo')) a lot. Would this be considered out of scope?

You can already do this: camelcaseKeys(o, {exclude: ['foo']}))

[kilianc]

exclude

Type: string[] RegExp[] Default: []

Exclude keys from being camelCased.

I meant excluding keys from the output object. Not just skipping the case change

[sindresorhus]

I see, no that's outside the scope of this module.
