We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
This patch adds the "-n"/"--head-count" optional argument to specifiy
the maximum number of shuffled lines to output.
Idea from Andreas' FIXME roulette :^)
Previously, shuf exclusively read input from stdin. This PR adds an
option to read from a file using Core::Stream::File. Since a file might
contain arbitrary bytes, including null bytes, this PR represents lines
as Spans of Bytes instead of Strings.
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

This was done with the `ambr` search and replace tool.
