Merge #284

284: Allow clippy::redundant_pub_crate r=taiki-e a=dnaka91

This is my first PR to this project so please bear with me. 

While using this crate in my project I noticed that the clippy::redundant_pub_crate (part of clippy::nursery) came up when I was using the derive macro in a module within a binary crate.

For example my trimmed down project layout is like this:
```
src/main.rs
src/services/log.rs <-- using the pin_project derive macro here creates a clippy warning
```

This change allows the clippy::redundant_pub_crate lint on all generated code to silence the lint messages. I hope this is the right spot to add the `#[allow(...)]` attribute.
