Add piano as a new instrument

This commit introduces a comprehensive database for piano chords, making it the third supported instrument in the library alongside guitar and ukulele.

Key changes include:

- **New Instrument Data:**
  - Added a complete set of piano chords under `src/db/piano/chords/`.
  - Created the necessary configuration files (`main.js`, `keys.js`, `suffixes.js`, `tunings.js`) to define the piano's properties and available chords.

- **Build Script Refactoring:**
  - Updated `tools.js` to handle different instrument structures. It now differentiates between processing fret-based chords (guitar) and note-name-based chords (piano).
  - Modified `generate.js` to correctly aggregate instrument-specific properties (like `keys` for piano) into the final `instruments.json` file.

- **Documentation:**
  - Updated `CHANGELOG.md` to version `0.6.0`, documenting the addition of the new instrument and the related build script enhancements.
