Missing options in cppcryptfsctl

[GlobalCBWK]

Hello,

Thank you for developing and maintaining cppcryptfs. It's a very useful tool.

However, I've noticed that many of the settings available in the GUI version (cppcryptfs) — such as Multi-threaded, Case insensitive, Enable fast mounting, and other options in the "Settings" tab — are not available in the command-line tool cppcryptfsctl.

This would greatly enhance the usability and consistency of the tool in headless or scripting environments.

Thanks again for your work!
