/**
* An extension of {@code DataInput} for reading from in-memory byte arrays; its methods offer
* identical functionality but do not throw {@link IOException}.
*
* Warning: The caller is responsible for not attempting to read past the end of the
* array. If any method encounters the end of the array prematurely, it throws {@link
* IllegalStateException} to signify programmer error. This behavior is a technical violation
* of the supertype's contract, which specifies a checked exception.
