Config doesn't support tabs

[Benjiko99]

Describe the bug

If the config file contains tab characters, the server will fail to start.

To Reproduce

Edit /etc/copyparty.conf and use tabs to align the comments instead of using spaces.

[global]
  e2dsa         # enable file indexing and filesystem scanning

The logs contain:

copyparty: error: unrecognized arguments: --e2dsa        # enable file indexing and filesystem scanning
