Commit e21a859ac9e5e05935612e0aba392d61dcf1f62a inadvertently introduced an off-by-one error in `internalEvalPolyLinearWithPrecomp`, which throws an exception when the polynomial to evaluate has degree 1 (it should only throw when the polynomial is of degree 0).
The following commit Fix evaluation of linear functions with `EvalPoly` · hsanzg/openfhe-development@b9bdf4d · GitHub fixes the issue and adds a test. I haven’t been able to submit it directly, because the GitHub repo doesn’t allow merge requests from external contributors.
