Type resulting object properties correctly when using change-case/keys

[dnjstrom]

When using change-case/keys I would love for the resulting object to be typed correctly without having to do an explicit cast. Currently all transformations produce unknown.

import { camelCase } from "change-case/keys"
import type { CamelCasedProperties } from 'type-fest';

const snake_cased = { foo_bar: 1 }

// Preferably the cast could be left off on the line below
const camelCased = camelCase(snake_cased) as CamelCasedProperties<typeof snake_cased>

console.log(camelCased.fooBar) // => 1
