Adding byte[] or Stream overload for Apply() argument

[longlongago-k]

Currently, only Func argument supported for telling patch file.
It seems strange for normal usage.
And also concerned about disposing opened stream via Func<>.

byte[] would be a reasonable overload, but does require the entire patch file to be in memory.

The patch method needs to read from three simultaneous positions in the Stream simultaneously; a forward-only or non-Seekable Stream would fail (and seeking a regular Stream might be inefficient).

All Streams opened by the Func<Stream> passed to the method are disposed automatically.
