Possible Variable Type Mistake in 3DS Example

[TheoKouzelis]

In the 3DS example the code suggests that the "enrolled" property will be a boolean

php-sdk/examples/3DS2-Challenge/charge.php

Line 72 in a150c33

if ($secureEcom->enrolled === true) {

But I believe the response variable, mapped to enrolled by the GpApiMapping class, will be a string of either ENROLLED, NOT_ENROLLED, NOT_ENROLLED_ATTEMPT or UNABLE_TO_VERIFY

php-sdk/src/Mapping/GpApiMapping.php

Line 497 in a150c33

$threeDSecure->enrolled = !empty($response->three_ds->enrolled_status) ?

Which means line 72 in the example will always equal false.

Response values for enrolled_status are being sourced from the docs here https://developer.globalpay.com/api/authentications#/Check%20Availability/check3DSAvailability

Maybe it should be rewritten to use the GlobalPayments\Api\Entities\Enums\Secure3dStatus values. Such as:
if ($secureEcom->enrolled === Secure3dStatus::ENROLLED) {

Other SDK's further downstream, such as the 3DS2 SDK seem to expect the parameter to be a boolean https://github.com/globalpayments/globalpayments-js/blob/master/packages/globalpayments-3ds/src/index.ts#L133:L135
