Okay, thanks - I'll take a look at that later.

One thought that just occurred to me: would it make sense to make a second
crypto template in rsa-pkcs1pad.c and call it "rsassa-pkcs1-v1_5" that does
this padding variant? It can share most of its code with the generic pkcs1pad

We could then also add a third variant "rsassa-pss" at a later date.
