e9e04b1445 applying lattigo-e patch 
CHANGELOG:
- Update of `PrecisionStats` in `ckks/precision.go`:
  - precision/error stats computed as log2 of min/max/average/...
  - fields renamed (`MinPrecision` -> `MINLog2Prec`, `MaxPrecision` -> `MAXLog2Prec`, ...)
  - `rlwe.Scale` has a `.Log2()` method
- Update of `mod1.Parameters` fields (made public, some removed)
- Improvement of the relinearization key-generation protocol (reduce the degree of the shares)
- Serialisation of bootstrapping keys
- Lower noise incurred by `ModUp`
- Evaluation keys can be compressed (public element `a` can be generated from a seed)
- More doc formatting
- Fix various bugs:
  - `ShallowCopy` of the CKKS bootstrapping evaluator and BFV evaluator not deep enough.
  - PSI example failing
  - Incorrect reset of pointer in uniform sampler
  - Error when doing inverse NTT with small degree
  - Mod1Evaluator changes the input ciphertext
