Register all Lua functions as a require-able module

• Collections: rs.filter, rs.sort, rs.map
• Text: rs.slugify, rs.word_count, rs.reading_time
• Environment: rs.env, rs.print, rs.is_gitignored
• Git: rs.git_info
• Content: rs.render_markdown, rs.rss_date, rs.html_to_text, etc.
• Images: rs.image_dimensions, rs.image_resize, rs.image_convert, rs.image_optimize
• Assets: rs.build_css
• Coroutines: rs.coro.task, rs.coro.await, rs.coro.yield, etc.
• Parallel (rayon): rs.parallel.load_json, rs.parallel.read_files, etc.
• Async I/O (tokio): rs.async.fetch, rs.async.read_file, rs.async.write_file, etc.
• Encryption: rs.crypt.encrypt, rs.crypt.decrypt, rs.crypt.encrypt_html
