This code is inspired by:

• https://github.com/flang-compiler/flang/blob/master/include/int128.h
• https://github.com/flang-compiler/flang/blob/master/lib/scutil/int128.c

This module is still WIP, it requires tests and discussion to get more operator overloading magic and how to better handle string-from/to,

Testing, feedback and contribs are welcome. But i hope to finish this soon and get this module merged into the official vlang branch.
