Temporary file/directory support

[heinezen]

Required Skills: Python or C++

Difficulty: Easy

It would be nice if we could create temporary files/directories in our current file system abstraction API. We currently only use temporary structures in the converter, but they could be useful in other places, e.g. for unzipping archives or on-disk caching.

Creation of temporary files could be implemented in our Python file API or our C++ file API or in both. The Python-side implementation is more preferrable at the moment, since the converter is written Python and temporary files already have an active use case there.

The easiest way to implement support probably is to add a method that calls the underlying system libraries for temporary file/directory creation:

• Python: tempfile module
• C++: std::filesystem and std::tmpfile

The retrieved path is then wrapped in our Path/Directory classes and returned by the method.

Tasks:

• Create temp file/dir and wrap them in openage file system API (Python)
• Create temp file/dir and wrap them in openage file system API (C++)
• Delete temp file/dir explicitely when object is destroyed
• Use new implementation in code (currently only in converter)
• (optional) Add method for checking if a file/dir is temporary

Hey @heinezen , I'm interested in working with this issue.
I'm new to open source but I've beginner level experience in working with Python and C++ both.
Can you please assign me this issue.

And also can you please elaborate more about the tasks that exactly what I've to do.
Thanks for your cooperation :)
