Function MainDialogPrompt

MainDialogPrompt(DIR: string, filename?: string): Promise<void>
Displays the main dialog prompt to the user, allowing them to select a task to run.

This function presents a menu of available tasks defined in MAIN_TASKS and executes the corresponding prompt based on the user's selection. It handles errors gracefully and recursively calls itself to keep the prompt active until the user chooses to quit.
Parameters
- DIR: string
  The directory path to be used for certain tasks. If not provided, it defaults to the current working directory.
- Optionalfilename: string
  An optional filename that can be used by certain tasks.
Returns Promise<void>
Example
```
// Calling the function to start the main dialog prompt
MainDialogPrompt('/path/to/my/directory', 'myFile.txt');
```
