buffer/slice



    cfunction

    (buffer/slice bytes &opt start end)
    
    Takes a slice of a byte sequence from start to end. The range is half
    open, [start, end). Indexes can also be negative, indicating indexing
    from the end of the end of the array. By default, start is 0 and end is
    the length of the buffer. Returns a new buffer.
