The C++ API for co-simulation and verification thru VPI interface

[ArcSpecter]

So I decided to write a modern C++ API utilizing the coroutines for writing a test code. Here goes my RapidVPI:
https://github.com/ArcSpecter/rapidvpi

Currently I only tested it with Iverilog, but theoretically it should work with any simulator supporting VPI.

The API library is very easy to install and easy to get start using it, I do provide template project which is very easy to copy and adapt. It is very enjoyable writing a highly abstracted C++ code and just have Iverilog interact with it on simulator level.

If someone needs help or wants to get started or needs help on how to use it with Iverilog - I can help with that.
