2.1.0

Adds the key subscription_group_state for setting the subscribed/unsubscribed status when using braze_subscription_groups in the Identify call.
- Use this value instead of subscription_state_id.
Adds support for nested custom attributes.
- If the object sent through Segment's Identify call has values that are of type [String: Any?], those values will be sent to Braze as a nested custom attribute.
- If the object sent through Segment's Identify call contains an array, the values of that array will be converted to strings, and the array will be reported to Braze as an array of strings.

2.0.0

Renames this repository from analytics-swift-braze to braze-segment-swift.
- This repository is now located at https://github.com/braze-inc/braze-segment-swift.
Adds the SegmentBrazeUI module, which provides the BrazeDestination plugin with BrazeUI support.
- Use the SegmentBraze module if you do not need any Braze-provided UI.
Adds two optional parameters to the BrazeDestination initializer:
- additionalConfiguration: When provided, this closure is called with the Braze configuration object before the SDK initialization. You can use this to set additional Braze configuration options (e.g. session timeout, push notification automation, etc.).
- additionalSetup: When provided, this closure is called with the fully initialized Braze instance. You can use this to further customize your usage of the Braze SDK (e.g. register UI delegates, set up messaging subscriptions, etc.)
- See the updated Sample App for an example of how to use these new parameters.
Adds support for automatically forwarding the advertisingIdentifier (IDFA) to Braze when making use of the IDFACollection Segment plugin.
Adds support to parse braze_subscription_groups in the Identity traits to subscribe and unsubscribe from Braze subscription groups.

Initial release.
