BUGFIX: [attribution-tools] Install gfortran, openblas, xsimd

[ckane]

Proposed changes

• Install openblas, gfortran, and xsimd in attribution-tools container

The build of the container for attribution-tools appears broken now, at least on ARM64 architecture. Not sure if it's also broken on x86-64 (I presume it is fine there?).

Installing dependencies OpenBLAS and gFortran seem to fix the breakage.

During fixing, I also noticed that some of the Python code will use xsimd if it is available. As this could potentially speed up analysis by leveraging streaming instructions, I figured I would add this as well to the container.

Checklist

• I consider the submitted work as finished
• I tested the code for its functionality using different use cases
• I added/update the relevant documentation (either on github or on notion)
• Where necessary I refactored code to improve the overall quality
