    Refactor to make it easy to drop in other encodings.
    
    I've recently found myself having to encode and decode a few times
    between binary data and straight-up ASCII hex, and this utility seems
    like a convenient existing place where I can drop that in as another
    option.
    
    Of course the name 'base64' then becomes slightly silly, but better
    that than make it so generic I can never remember it.

    Add --hex (and --HEX) encoding options.
    
    I've set the partial fill character to '0', which means that an input
    consisting of an odd number of hex digits will be treated as if it has
    a trailing '0', so the last hex digits will be the MSB of a byte.
    
    This is a bit odd, but I think less odd than the alternative of
    treating it as the LSB; this way, there's a more consistent answer to
    the question 'if _this_ hex digit became _those_ four bits of the
    output file, where can I find the four bits corresponding to the
    next/previous one?'

    Remove chars-per-line divisibility constraint.
    
    It was only laziness that made me put it in in the first place; it's
    pretty trivial to get rid of it, so while I'm here, why not?

    Fix spurious newline output when encoding no data.
    
    In the encoding output loop, we now print the \n _after_ rather than
    before each character. The effect is that where previously we would
    always end the loop with a partial line output _except_ when the loop
    ran zero times (hence the bug due to overlooking that special case),
    we now end the loop with a partial line output only if the last line
    is not a multiple of cpl, so the condition for needing a trailing
    newline is simply that column > 0, which doesn't require us to count
    the input bytes.
