Running cargo test on the current master brach (and on the last three releases), I get two test failures. One is described in #236, for the second I didn't find an issue yet, so I'm reporting it here: modular_arithmetic::tests::complement_of_complement_is_the_original_test is broken, and actually has been since commit f97b7ca of September 2024.

Setting nbits to 254 (the state before said commit) makes the test pass — however, I'm unsure about correctness implications.
