0.0.7: Provide start, end, & runtime duration logging for thread

- ==> If you want to mute logging this message to the terminal for all ThreadWithResult instances, set the `log_thread_status` class attribute to False:

```
ThreadWithResult.log_thread_status = False
```
- ==> If you only want to mute logging this message to the terminal for a specific instance of ThreadWithResult, set the `log_thread_status` attribute for the specific instance to False:

```
thread_with_result_instance.log_thread_status = False
```
- Keep in mind python prioritizes the `log_thread_status` instance attribute over the `log_thread_status` class attribute!
- ==> If you want to log this message to an output file (or multiple output files) for all ThreadWithResult instances, set the `log_files` class attribute to an iterable object contatining objects that support the `.write()` method:

```
ThreadWithResult.log_files = [file_object_1, file_object_2]
```
- ==> If you only want to log this message to an output file (or multiple output files) for a specific instance of ThreadWithResult, set the `log_files` attribute for the specific instance to an iterable object contatining objects that support the `.write()` method:

```
thread_with_result_instance.log_files = [file_object_1, file_object_2]
```
- Keep in mind python prioritizes the `log_files` instance attribute over the `log_files` class attribute!

- release 0.0.7 also removes the irrelevant "Operating System :: RISC OS" PyPI classifier
