Disambiguate fmt logging methods that are using variadic templates.

As variadic template arguments can be zero length, we need to specify that at least one fmt argument is provided, to distinguish these methods from the existing trivial method that takes no fmt arguments.

Without this, static analysers such as ReSharper flag the logging calls as errors.

Update README.md
