Notes for Reviewer

This PR adds distinct overloads for LogStream& operator <<. This enabled implicit type conversion to the underlying type of e.g. Wrapper<T> if the implicit operator T() is implemented.

Additionally, it is finally possible to log char instead of only signed char and unsigned char.

I found some typos, but you can ignore my comment and merge if there's nothing else to change.

LGTM, only minor nitpicks. From my side we can merge this.
