import { TarEntry } from "https://deno.land/std@0.224.0/archive/mod.ts";
Reads up to p.byteLength bytes of the tar entry into p. It resolves to
the number of bytes read (0 < n <= p.byteLength) and rejects if any
error encountered. Even if read() resolves to n < p.byteLength, it may use
all of p as scratch space during the call. If some data is available but
not p.byteLength bytes, read() conventionally resolves to what is available
instead of waiting for more.
