Recompute the secret from at least minSigners secret shares (inside
KeyPackages) using Lagrange interpolation.
This can be used if for some reason the original key must be restored; e.g.
if threshold signing is not required anymore.
This is NOT required to sign with FROST; the point of FROST is being
able to generate signatures only using the shares, without having to
reconstruct the original key.
The caller is responsible for providing at least minSigners packages;
if less than that is provided, a different key will be returned.
