Phase 1

Write code that uses clap to parse the command line arguments and create a DrawerOperation struct from them. The DrawerOperation struct will contain:

• An operation_type (OperationType, enum of Open or Close)
• A drawer_file (Path for the drawer file to open or close)
• A key_path (Path to the key we'll use, which is either the value of the -i flag or the value of the $DRAWER_KEY env var)
• A target_path (Path to the contents we're going to put into or take out of the drawer)
• A force (bool for whether or not -f was passed)

In order for this to be testable, it needs to be a function that returns a Result<DrawerOperation, DrawerError>. The main function should call that and then do nothing with the result.

Certain things should cause the function to return Err:

• Not passing a drawer file
• Passing a subcommand other than open or close
• Passing any flags but -f or -i
• Not passing -i when the $DRAWER_KEY environment variable is undefined
