Dev serialization (#64)

* Added compressed serialization for GLWECiphertext + Ciphertext decompression

* Added compressed serialization for GGLWECiphertext & GLWESwitchingkey

* generalized automorphism test

* Removed ops on scalar_znx, replaced by as_vec_znx/as_vec_znx_mut and then call op on vec_znx

* Added tests for automorphism key encryption

* Added tensorkey compressed

* added ggsw compressed
