import { Buffer } from "https://deno.land/x/esm@v97/server/embed/types/node.ns.d.ts";
Returns a buffer which is the result of concatenating all the buffers in the list together.
If the list has no items, or if the totalLength is 0, then it returns a zero-length buffer. If the list has exactly one item, then the first item of the list is returned. If the list has more than one item, then a new Buffer is created.
