expected enum winapi::ctypes::c_void, found enum std::ffi::c_void

[thy1037]

When I add tokio-modbus as a dependencies, cargo build will failed.

Reproduction:

1. cargo new a new project
2. add tokio-modbus = "0.5.3" to Cargo.toml
3. copy the example tcp-client code to main.rs
4. run cargo build, and show:

Probably caused by tokio-rs/tokio#5204.

Confirmed: https://github.com/slowtec/tokio-modbus/actions/runs/3647400977/jobs/6159588455

Please try to pin your tokio version to 1.22.0 until the incompatibilities have been resolved.

Please try to pin your tokio version to 1.22.0 until the incompatibilities have been resolved.

Add tokio = {version = "=1.22.0", features = ["full"]} to Cargo.toml, the incompatibilities can be resolved.

But running has problem, create a new issue #138

Fixed by #139.
