Support for bivariate convolution & normalization with offset (#126)

Browse Source 
* Add bivariate-convolution
* Add pair-wise convolution + tests + benches
* Add take_cnv_pvec_[left/right] to Scratch & updated CHANGELOG.md
* cross-base2k normalization with positive offset
* clippy & fix CI doctest avx compile error
* more streamlined bounds derivation for normalization
* Working cross-base2k normalization with pos/neg offset
* Update normalization API & tests
* Add glwe tensoring test
* Add relinearization + preliminary test
* Fix GGLWEToGGSW key infos
* Add (X,Y) convolution by const (1, Y) poly
* Faster normalization test + add bench for cnv_by_const
* Update changelog
