rtu non-functional when used about tokio-modbus

[flosse]

It looks like you are using tokio_modbus v0.1.0 that has a different API.
The current master branch should lead to v0.2.0 but first these issues should be closed:

• tokio-rs/tokio-proto#204
• tokio-rs/tokio-proto#202
• tokio-rs/tokio#118

So in your case you can either use the v0.1.0 API (example) or point the tokio-modbus dependency to the git repo:

[dependencies.tokio-modbus]
version = "*"
git = "https://github.com/slowtec/tokio-modbus"
default-features = false
features = ["rtu"]

I just published v0.2.0 so you can use it as usual :)
