Add a batch verifier to multiexp, along with constant time variants

Browse Source 
Saves ~8% during FROST key gen, even with dropping a vartime for a 
constant time (as needed to be secure), as the new batch verifier is 
used where batch verification previously wasn't. The new multiexp API 
itself also offered a very slight performance boost, which may solely be 
a measurement error.
