Version-lock all dependencies (`S1` broken after package update)

Student group had a corrupted Pi
@JudCF reflashed it according to X0 etc.
sudo pbl install && pbl test runs and passes all tests
But the test suite doesn't actually execute an ML image analysis, so the test suite doesn't load the underlying C/C++ libraries behind the image inference
And google updated tflite-runtime last night from 2.11.0 (released Dec2022) to 2.12.0
And that is problematic, because 2.12.0 depends on GLIBCXX symbols that aren't provided by the base raspbian install (assumption: they are compiling it on a newer distro, or cross-compiling it with a newer C++ library)

Solution:

Quick, but undesirable long-term: version-lock tflite-runtime to 2.11.0 in the installation script (here:https://github.com/PortableBalanceLab/PBL/blob/9cd3dede97fb31c7fed637b2e37129cf9ff44438/X0_SoftwareSetup/pbl/pbl/s1.py#L25)
Middle-ground, post issue with tflite-runtime and convince them to version-lock their C++ library in their build process
Best: hope rasbian ships a newer C++ library via apt, which will make this problem magically go away with apt upgrade
