Pls selection overhaul, build system almost "user-friendly"
In this release :
- Parameter estimation precision display with 6 digits (fix #8)
- PLS new heuristic selection as discussed there #9
Plus :
- reworked the whole vcpkg dependancy and now it's bootstraped to be downloaded and launched directly in the cmake build
- made the MKL and static stuff (which currently requires clang and libc++ on linux) optional
Hopefully anybody could compile the project with a c++17 compliant compiler. - static binary with threaded MKL provided (linux only at the moment) : blazing fast PLS!
