Updated the README example with acquire connection (#99)
* Updated the README example with acquire connection

Initially from reading the docs and examples I tried to use `&mut pool` instead of `&mut conn`. The compiler gave me an error that `Pool<MySql>` didn't implement `Executor`. I had to do a bit of digging and eventually just viewed the source of `Pool` to find `acquire()`, `try_acquire()` etc.

I think this change makes it a bit easier for someone to get started.

* Update README.md to reference initial pool declaration

* Fixed compile issues and added examples of using &mut &pool
