Title: added the observer, passing the expanded list of data, not only the time...

... and *args

```
PulseMeter::Observer::Extended.observe_method(Class, :method, sensor) do |p|
# p is a Hash with keys:
# :self -- the ref to the object with call :method (or class if use observe_class_method)
# :delta -- execution time in milliseconds
# :result -- :method return value
# :args -- list of :method arguments
# :exception -- exception object or nil
end
```
