Bare-bone REAPER extension (prints Hello World! using the API)
// Bare-bone REAPER extension
//
// 1. Grab reaper_plugin.h from https://github.com/justinfrankel/reaper-sdk/raw/main/sdk/reaper_plugin.h
// 2. Grab reaper_plugin_functions.h by running the REAPER action "[developer] Write C++ API functions header"
// 3. Grab WDL: git clone https://github.com/justinfrankel/WDL.git
// 4. Build then copy or link the binary file into <REAPER resource directory>/UserPlugins
