LRU Cache with Photo Storage
Implement an LRU cache with a `put(byte[] photo)` method that persists a photo to memory and returns a generated unique ID (UUID), and a `get(String id)` method that retrieves the photo by ID. The LRU eviction policy should be based on the total size of the stored photos in bytes, not the number of entries in the cache.

LRU cache implementation for the put(byte[] photo) also persist in memory and generate id(UUID or global id) get(string id) return the photo. LRU eviction is based on the size of photo not the size of hashmap.
