Changed
- Use solana 1.16.0 [(61)](https://github.com/kevinheavey/solders/pull/61)
- Rename `process_transaction_with_metadata` to just `process_transaction`.
Remove `process_transaction_with_preflight` and the old `process_transaction`
which had too many footguns. The new `process_transaction` uses the Rust
`process_transaction_with_metadata` under the hood. [(60)](https://github.com/kevinheavey/solders/pull/60)
Fixed
- Remove `.string()` from `pubkey.pyi` as the method no longer exists [(57)](https://github.com/kevinheavey/solders/pull/57)
- Fix `pre_token_balances` getter [(59)](https://github.com/kevinheavey/solders/pull/59)
