Port ProtoGalaxy from https://github.com/arnaucube/protogalaxy-poc adapting it to the current folding-schemes lib (#37)

Port ProtoGalaxy initial version from
https://github.com/arnaucube/protogalaxy-poc adapting it to the current
folding-schemes lib, which is a first iteration that implements the
Lagrange-basis version from
[ProtoGalaxy](https://eprint.iacr.org/2023/1106) folding scheme.  There
are some pending optimizations, but is a first step towards integrating
ProtoGalaxy in the library.
