Dependency on ninja for building openbtmixing

[asemposki]

When testing Taweret on a Linux cluster with a preconfigured MPI implementation, @jared321 found that meson could not find ninja, whereas on macOS it was already installed by homebrew. Jared used python -m pip install ninja to remedy this, but pointed me to the issue in Bfrescox under Issue 20 (found here, and the PR associated with it is at this location) where they solved this issue. @jcyannotty this might be worth fixing in the future for those running on a Linux cluster or other machine not already pulling in ninja.

A fix for this issue has been merged into main by PR #20. Pending tasks to finalize this fix and close this Issue are

• Confirm that all actions are passing on main at the merge commit
• @jcyannotty to release the resulting v1.1.3 version of OpenBTMixing Python package on PyPI
• @jared321 to update Taweret actions on Taweret feature branch 148OpenBTUpdates to install v1.1.3 directly from PyPI to confirm that Taweret is working correctly with this fix as desired
• @jared321 to confirm via manual testing that Taweret can be installed with no need to preinstall meson or ninja and that it can be built with no eigen installation as well as with preexisting eigen v3 and v5 installations.
• @jared321 to confirm that Taweret and SmoothEmulator installations can no longer enter into conflict due to eigen installations.
• @jared321 and @asemposki to merge 148OpenBTUpdates into Taweret's main branch

@jcyannotty Please proceed with release on PyPI.

All required changes have made their way into the respective main branches of both OpenBTmixing and Taweret. This has included extensive testing of different installation options.
