Add CloneCommand for initializing and syncing Rojo projects

- Introduced a new `CloneCommand` struct to facilitate the creation of Rojo projects from Roblox places, combining initialization and syncing in a single command.
- Implemented functionality to fetch experience names from the Roblox API and sanitize them for valid folder names.
- Added command-line options for specifying place ID, project path, project kind, and options to skip git initialization and cursor rules.
- Updated the CLI module to include the new `CloneCommand` and handle its execution within the command structure.
- Included tests for the sanitization function to ensure proper handling of various input cases.
