chore: Adjust tsconfig and Mocha settings for ESM support (#10)

- Updated tsconfig.test.json for CommonJS module resolution.
- Modified Mocha test script to ensure correct tsconfig is used.
- Attempted various configurations to resolve ESM loader issues with Node v18.16.0.

Note: Further investigation may be needed to fully support ESM with the current Node version.
