util to create ZFOutput for custom impl, useful for script

impl's params: (see ZFOutput)

• param0 holds a v_zfstring indicates a source that impl should output
• param1 holds a v_zfindex indicates the source's size
• result holds a v_zfindex that has source length as init value, impl may update the result value to indicates bytes actually written

this is useful for script to supply IO logic, lua for example:

ZFOutputForImpl(function(zfargs)
    local src = zfargs:param0()
    local size = zfargs:param1()
    local result = zfargs:result()
    local yourWrittenLength = yourOutput(buf, count)
    -- return size actually written
    result:zfv(yourWrittenLength)
end)
