feat: Subject Segmentation

Subject Segmentation based on issue #586

ML Kit's subject segmentation API allows developers to easily separate multiple subjects from the background in a picture, enabling use cases such as sticker creation, background swap, or adding cool effects to subjects. Read more

Key capabilities

• Multi-subject segmentation: provides masks and bitmaps for each individual subject, rather than a single mask and bitmap for all subjects combined.
• Subject recognition: subjects recognized are objects, pets, and humans.
• On-device processing: all processing is performed on the device, preserving user privacy and requiring no network connectivity.

This API requires Android API level 24 or above. Make sure that your app's build file uses a minSdkVersion value of 24 or higher
