Binary Search Tree implementation in Rust. For fun and to practice Rust programming.

The plan is as follows:

1. Have a working BST implementation:
   • ✅ Insertion
   • ✅ Removal
   • ✅ Search
   • Secondary operations:
     • ✅ .clear()
     • ✅ .contains()
     • ✅ .len()
     • ✅ .is_empty()
   • Iterators:
     • ✅ .iter()
     • ✅ .into_iter()
     • ✅ .from_iter() (and .collect())
     • ✅ .extend()
     • ✅ .iter_mut()
2. Implement Self-balancing using the AVL method:
   • ✅ Insertion
   • ✅ Removal
3. Add serialization and deserialization from/to bytes:
   • ✅ Serde traits implemented for BSTMap and BSTSet (implementation gated with serde feature flag)
4. Try sending it over a network, writing to a file or some other way of IPC/data sync
   • Perhaps a simple Redis-style key-value store with persistence to disk?
5. Optionally: make the code pretty :)
