Circular buffer

Prerequisites

1. Complete this README.md by documenting how to build and run.
2. Use any build tool (e.g. make).
3. The code should compile cleanly, no errors/warnings.
4. Static memory only, no malloc()/new.
5. Open a pull request with your changes.
6. Use C++

Coding task

1. Write a circular buffer class with the following features:
   1. Compile time fixed size
   2. Static memory allocation only
   3. Generic data type (e.g. uint8_t)
   4. Two put(data) overflow behaviors: overwrite and discard data.
2. Write tests showing your circular buffer in action.
