  1. Performance improvements for Richelot isogenies 

    We can eliminate variables by simple substitutions
using the symmetric function identities. This eliminates
Gröbner basis computations.

Also use the appropriate jacobian() method and avoid creating
each Jacobian twice.

Execution speed is up by 50%-60%.
