Release v5.0

Finally after nearly two years, a new release of STC! It has lots of improvements, new features and bug fixes. There are a number of breaking changes since the last released version, so make sure to check out the version history. Special thanks to all who contributed with PRs, bug reports and suggestions!

New Features in v5.0**

• New main build system with Meson. Simple Makefile provided as well.
• New sum type (tagged union), included via algorithm.h
• New single/multi-dimensional generic span type, with numpy-like slicing.
• Coroutines now support structured concurrency and symmetric coroutines.
• Coroutines now support error handling and error recovery.
• Template parameter i_type lets you define i_type, i_key, and i_val all in one line (comma separated).
• Template parameters i_keyclass and i_valclass to specify types with _drop() and _clone() functions defined.
• Template parameters i_keypro and i_valpro to specify cstr, box and arc types (users may also define pro-types).
• hmap now uses Robin Hood hashing (very fast on clang compiler).
• Several new algorithms added, e.g. c_filter (ranges-like).
• A lot of improvements and bug fixes.
