Added Additional Base Functionality

[inspectorG4dget]

Added functionality:
All prints now show the filename, function, line number, and description

• I have visited the source website, and in particular
  read the known issues
• I have searched through the issue tracker for duplicates
• I have mentioned version numbers, operating system and
  environment, where applicable:

  import tqdm, sys
  print(tqdm.__version__, sys.version, sys.platform)

• If applicable, I have mentioned the relevant/related issue(s)

Maybe nice to have as an example of extending tqdm but don't really see this in core. Could you move this to the examples/ folder?

[inspectorG4dget]

In fact, I've added my extensions to patch.py by subclassing the main class, so that it does not conflict with mainline development/API. The proper way to use this patch would therefore be from tqdm.patch import tqdm, print.

In any case, I will add some usage examples to show how this works
