Type 'string[]' is not assignable to type 'MultiFieldSelector'.

Describe the bug When using TypeScript the "pluck" should be able to accept an object with keys that have an array of strings according to the ReQL documentations here. Such as

.pluck({ key: ['nested_key', 'second_nested_key', ...] })

but instead, it errors with the following

Type 'string[]' is not assignable to type 'MultiFieldSelector'.
  Type 'string[]' is not assignable to type '{ [property: string]: MultiFieldSelector; }'.
    Index signature is missing in type 'string[]'.ts(2322)

To Reproduce Steps to reproduce the behavior:

See the Describe the bug section above.

Expected behavior Any method that allows providing nested object values, should also be allowed to accept the shorthand form.
