/**
 * Removes the first `N` elements from a tuple type. Does not return the removed types.
 *
 * @remarks Its worth noting `Pop`, `Push`, `Shift`, and `Unshift` are inspired by JS; however, the types are not 1:1 for design reasons. More information can be found in [README](
 * @example
 * ```
 * declare const tuple: ['d', 'a', 'v', 'i', 'd']
 * type Tuple = ShiftN<typeof tuple, 2> // ['v', 'i', 'd']
 * ```
