chore: add package boilerplate

Adds initial Node.js package boilerplate. Here's a highlight of what's
included:

- Uses `npm` package manager for managing dependencies and scripts
- Dual-module system support via TypeScript transpilation
- Uses `gts` for linting
- Uses `typescript` package to transpile TypeScript files
- Uses `c8` for coverage support
- Uses `tap` test runner
- Setup initial GitHub Actions workflow for running ci tests
