Mirrors the C++ enum SecurityLevel in
core/lattice/stdlatticeparms.h.
Value
A named list of 7 integer scalars, each the value of the
OpenFHE C++ enumerator of the same name. An element names the
number of bits of security the ring dimension is chosen to provide
against a classical (HEStd_*_classic) or quantum
(HEStd_*_quantum) adversary, following the HomomorphicEncryption.org
standard tables. HEStd_NotSet skips the table lookup, in which
case the ring dimension must be set explicitly. Pass an element as the
security_level argument of CKKSParams(), BFVParams(),
BGVParams() or fhe_context().
