WooCommerce Selfie Upload on Registration

This code is a WordPress plugin called "WooCommerce Selfie Upload" that extends the WooCommerce registration form by adding a mandatory selfie upload field. The plugin modifies the registration form by adding the necessary enctype attribute to allow file uploads. It also adds a file input field to the form, specifies its accepted file types (JPG and PNG), and makes it required. The plugin includes validation to check if a valid selfie image was uploaded and displays an error message if not. After successful registration, the plugin saves the uploaded selfie file as an attachment in the media library and associates it with the user's profile by storing the attachment ID in user meta. Lastly, it displays the uploaded selfie image in the admin user profile.
