This plugin adds a specialized phone number field type for the Advanced Custom Fields plugin, designed for developers building forms that require international phone number input. It replaces basic text fields with a validated input that ensures data quality and consistency.

• Real-time Validation and Formatting: Uses the libphonenumber library to check numbers for correct format as users type, preventing invalid entries from being submitted.
• Country Detection and Flag Display: Integrates intl-tel-input to show a dropdown with country flags and codes, making it clear which country's format is being used.
• Structured Data Output: Returns the phone number as a structured object containing multiple standardized formats (E.164, national, international, RFC3966), ready for display or storage.
• Default Country Setting: Allows developers to pre-select a default country for the input field, improving the user experience for a target audience.
• Placeholder Customization: Supports setting a custom placeholder text within the input field to guide users on the expected format.
