Bugfix: no module named entities

[niloysh]

What does this commit address?

Version 3.2.0 of the ricxappframe (which is also available for download from pypi here) has issues with importing RMRXapp, rmr and Xapp.

It complains as follows:

no module called ricxappframe.entities

This commit fixes this.

@niloysh From my understanding, this is just a mirror from the official Gerrit repository from the O-RAN SC. That is to say, I am not sure if the ORAN SC maintainers are even looking at the issues posted here.

Nevertheless, I faced the same issue you did when importing of the xApp Frame v3.2.0, as Python can't load the entities directory without the init.py files.

I've submitted a fix for this on their Gerrit repo months ago, but the maintainers still haven't incorporated my changes to the codebase. 🤞🏻

@santos-j Thanks! I'll look into the Gerrit repo.
