It took a bit but I found it: this has been promised in a comment in #498. But what are two years between friends?

My implementation of the extra strong Lucas test has been successfully checked against all Miller-Rabin pseudoprimes to the base 2 up to 2^64.
Testcode in a gist. Comment contains links to the pseudoprime lists.

There are many preprocessor branches now in mp_prime_is_prime.c. Add a line or two to the CI to check the branch LTM_USE_ONLY_MR?

The generated SPRP tables including their factoring (used to compute some of the limits here) is in the new repository SPRPs.

There are no changes of the API directly but the Frobenius-Underwood test is an addition to the Extra-Strong-Lucas test now, instead of an alternative. If that is not seen as a problem we could merge it now instead of later (version 2).

Oh, and I found a bit of an unrelated mess in the documentation and fixed it here instead of a separate PR. Drop me a note if you[1] want a separate PR.

[1] "You"? Who is "you"? Y'all, of course! ;-)
