remove Boost?

[wztzjhn]

The only place for Boost here is only a root solver, which can be replaced by a simple hand-coded binary search: the density versus mu function is monotonic.

Similarly, the Boost dependency in Kondo repo can be removed, since c++17 already supports "filesystem". Standing at 2022, c++17 is quite well implemented in major compilers.

This may greatly reduce the installation barrier for many users (boost filesystem never worked out of the box in most the HPC's in my experience, always requireed a manual installation).

This seems like a good idea to me. I think Boost was more needed in the Kondo repo, for things like file/directory access?

[wztzjhn]

The file/directory access is included in c++17 in std::filesystem. So if we require c++17 instead of c++11, we can replace all boost::filesystem by std::filesystem.
