[Improvements]: Remove usage of boost library

[Milerius]

Motivation

Most of the use of boost in the project is replaceable by our own implementations or the standard library.

This passing of dependencies in the project allows us to have more sovereignty, simplify security audits and facilitate compilation in wasm and facilitate the distribution/compilation of the project.

• [x] boost::variant -> std::variant #2565
• [x] boost::any -> std::variant #2539
• [ ] boost::algorithm -> std alternative / ranges
• [x] base64 -> easy to recode (good test task) #2883
• [ ] boost::lexical_cast -> can be recoded or replaced with std::to_string, std::to_chars alternative (good test task for candidate)
• [ ] boost::uuid -> single header file for uuid to recode (good test task for candidate)
• [x] boost::crc -> easy to recode - Under review #2629
• [ ] boost::multiprecision -> https://blog.llvm.org/2020/04/the-new-clang-extint-feature-provides.html (good test task) - https://godbolt.org/z/fanj71nE9

Nice wrap up , can you sort them from easy/small to hard? so we can tackle one by one
