Automated Python to Mojo translator

[msaelices]

A configurable tool to automatically convert Python code to the new Mojo programming language.

https://github.com/msaelices/py2mojo

So, consider this tool experimental; I've just spent about 4-6 hours implementing it.

Please do not trust the generated code and double-check it, both because the tool has been recently created, and Mojo still needs to support the entire Python language, so it's not still a superset of Python. I will try to improve it on weekends, but any help would be very welcome.

Examples of things that are not still working:

• Anything that will work in the future, like the classes or dictionaries that are not still supported. My approach is not to try to convert them if not configured, as it will be supported in the future.
• Imports from Python libraries, as the let x = Python.import_module('xxx') approach is not valid in the scope of a module. Please read this proposal as a potential way to solve it: Feature Request: streamline importing python code and type annotations #298
