Add skipExternalValidations flag

[Megamind51]

This PR adds a skipExternalValidations flag to allow users to skip external API calls and use only internal regex-based validation for EU TINs. This reverts the changes from commit 3de621c (PR #28) which forced all EU countries to use internal validation. The new approach restores external API validation as the default for most countries while giving users the option to skip it when needed (e.g., for performance, offline scenarios, or testing).

Pull request overview

This PR adds a skipExternalValidations flag to allow users to skip external API calls and use only internal regex-based validation for EU TINs. This reverts the changes from commit 3de621c (PR #28) which forced all EU countries to use internal validation. The new approach restores external API validation as the default for most countries while giving users the option to skip it when needed (e.g., for performance, offline scenarios, or testing).

Changes:

• Added skipExternalValidations parameter to mask() function with default value of false
• Modified EU TIN validation logic to check both config.validateInternally and skipExternalValidations flags
• Removed validateInternally: true flags from most natural-person country configs (reverting PR #28), while keeping them for countries that must always use internal validation (BG, GB, IS, LI, NO)
• Unskipped tests that verify external API validation behavior for countries without validateInternally flag
• Added tests for the new skipExternalValidations flag behavior
