qcd.mul1 fails on Apple M1

[certik]

I installed Taco on Apple M1 Max using:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON=ON ..

And tested using ctest. All tests pass, except:

$ ctest -R qcd.mul1 -V

I'm not sure anyone on the development team right now has an M1 mac to reproduce this issue. However, it looks like a small precision error that seems ignorable?

Yes, it seems the test should be fixed to account for these small errors.
