I noticed that we were taking `TimerCb` as a `const&` and then copying that into the member. This is completely fine when the constructor is called with an lvalue. However, when called with an rvalue, we can allow the `std::function` to be moved into the member instead of falling back to a copy, so I changed the constructors to take in universal references. Also, `std::function` constructors can take in multiple arguments, so I further modified the constructors to use variadic templates.
