This crate will be REMOVED in Agave v4.0.0 and its name will be taken by the BPF Stake Program. \
            Users of this crate's public exports must switch to:
* `stake_state` -> `solana_stake_interface::state`.
* `points` -> `solana_runtime::inflation_rewards::points`.
* `id()` / `check_id()` -> `solana_stake_interface::program::_`.
* `get_minimum_delegation()` will continue to live at the same path.
* Some convenience functions such as `stake_from()` and `create_account()` are removed."
