Pip package conflict

Created by: jordancarlin

With recent updates made to riscv-isac (https://github.com/riscv-non-isa/riscv-arch-test/pull/514), there is now a package dependency conflict between riscv-isac and matplotlib. See error message below.

INFO: pip is looking at multiple versions of riscv-isac to determine which version is compatible with other requirements. This could take a while.
Collecting matplotlib>=3.9.0 (from -r /home/runner/work/cvw/cvw/bin/requirements.txt (line 4))
  Downloading matplotlib-3.9.1.post1-cp311-cp311-manylinux_2_17_x86_64.manylinux2014_x86_64.whl.metadata (11 kB)
  Downloading matplotlib-3.9.0-cp311-cp311-manylinux_2_17_x86_64.manylinux2014_x86_64.whl.metadata (11 kB)
ERROR: Cannot install -r /home/runner/work/cvw/cvw/bin/requirements.txt (line 4) and -r /home/runner/work/cvw/cvw/bin/requirements.txt (line 6) because these package versions have conflicting dependencies.

The conflict is caused by:
    matplotlib 3.9.0 depends on packaging>=20.0
    riscv-isac 0.18.0 depends on packaging==19.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip to attempt to solve the dependency conflict
