Update MIDI message handling and version increment

Refactored MIDI message classes to improve modularity and flexibility, introducing separate classes for distinct MIDI message types. Updated `build.gradle.kts` version to `0.2.0` to reflect these changes. Removed `.idea/.name` file as part of cleanup.
