PartialReader passes uninitialized memory to user-provided Read

Affected versions of this crate passed an uniniitalized buffer to a user-provided Read instance in PartialReader::read.

This can result in safe Read implementations reading from the uninitialized buffer leading to undefined behavior.

The flaw was fixed in commit 39d62c6 by zero-initializing the passed buffer.
