Current behavior

Passing in a bytes > 1 PB or passing a from unit of PB or EB will cause the pipe to fail.

Expected behavior

The pipe correctly transforms bytes to PB and EB

Minimal reproduction of the problem with instructions
Call BytesPipe using 8 EB.
new BytesPipe().transform(8, 2, "EB")

What is the motivation / use case for changing the behavior?

When dealing with large storage devices there are scenarios when bytes need to be translated to PB or EB.
