Support Microblink detector

[ccen-stripe]

Summary

Use Microblink detector along with IDDetector. Wrap IDDetector's output with Legacy and Modern types, when MB is available, emit Modern types.

When Modern is available, don't manually crop the image, but use the extracted image from MB for user_upload image

This change requires a new dependency CaptureCore from capture-ios from microblink, made the following changes to support it

• Added it as a binaryTarget in Package.swift - this change adds the dependency to SPM integration
• Added it as a StripeIdentity.podspec - this change adds the dependency to cocoapd integration
• Added CaptureCore as a spm dependency in StripeIdentity.xcodeproj - this change makes sure the dependency builds in xcode
• Added CaptureCore as a spm dependency in IdentityVerification Example.xcodeproj - this change makes sure the dependency builds in xcode
