By enabling global-sops-mode, sops-mode will try to enable itself automatically when we enter a SOPS encrypted file. When you see that sops is enabled you can use sops-edit-file to decrypt the file. After modifications have been made you can save with sops-save-file or discard modifications with sops-cancel. Sops encrypted files will be shown in read-only-mode to prevent the user from accidentally corrupting an encrypted file. This is useful for partly encrypted files, where only a single line might be encrypted.

• Add a variable to auto-decrypt when we enter an encrypted file when global-sops-mode is enabled.
• Create new SOPS encrypted files via sops-mode.
• If we fail to encrypt (sops < 3.9), we need to revert changes to original-file to encrypted state and switch back to decrypted buffer.
  • We should also show the error buffer too.
