DFlow AMM interface

Rust crate for the Amm trait to integrate with dflow-core.

Integration Overview

Amm trait implemenation:

1. Create the AMM instance: from_keyed_account parse the pool/market account and create AMM for pool
2. Provide pool metadata: label, program_id, key, and get_reserve_mints to identify pool
3. Handle state updates: get_accounts_to_update list accounts needed for quotes, then update to deserialize and cache market/pool states
4. Provide quotes: quote to calculate swap output amounts based on current market/pool state
5. Generate swap instructions: get_swap_and_account_metas to return the swap instruction type and required accounts

Important Conventions

Quote Method

quote.in_amount <= quote_params.amount.

When implementing the quote method, use input capping if the requested input amount cannot be fully consumed (e.g., due to liquidity limits or other constraints). Return a Quote with in_amount less than the requested amount rather than returning an error or panicking.
