v2.0.0

BREAKING CHANGE

Version 2.0.0

1. Rename Map->Dict, Integer->Int, String->Str, consistent with the Python name.
2. Optimize as much as possible using standard library templates and algorithms.
3. Refactor with C++20.
4. Use Rust doc-comments style for conciseness.
5. More functionality, cleaner code, faster speed.

v1.6.1

1. Fix bug in List::operator>>=()/<<=().
2. Remove String::set()/get().
3. Optimize performance.
4. Simplify dependencies.

This is the last version that uses custom data structures and requires C++17.
