util to create ZFInput for custom impl, useful for script

impl's params: (see ZFInput)

• param0 holds a v_zfstring let impl to output
• param1 holds a v_zfindex that indicates the ZFInput's input length, or zfindexMax to calculate the total input length
• result holds a v_zfindex indicates bytes actually read

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

ZFInputForImpl(function(zfargs)
    local buf = zfargs:param0()
    local size = zfargs:param1()
    local result = zfargs:result()
    if zfl_eq(size, zfindexMax()) then
        -- return total input size
        result:zfv(yourTotalLength)
        return
    end
 
    -- write to the buf
    buf:append(yourData, size)
    -- return written length
    result:zfv(yourWrittenLength)
end)
