split: add new --hex-suffixes option
* doc/coreutils.texi (split invocation): Document the new option.
* src/split.c (usage): Likewise.
(main): Process the new option much like --numeric-suffixes,
but with an adjusted alphabet.
* tests/split/numeric.sh: Refactor to support --hex mode.
* NEWS: Mention the new feature.
