Returns a new `Buffer` that references the same memory as the original, but
offset and cropped by the `start` and `end` indices.
Specifying `end` greater than [`buf.length`] will return the same result as
that of `end` equal to [`buf.length`].
*Note*: Modifying the new `Buffer` slice will modify the memory in the
original `Buffer` because the allocated memory of the two objects overlap.
