rust: Bump Solana crates to v2.1 (#13)

#### Problem Version 2.1 of the Solana crates is out, but all of the Rust programs are still on v2.0. #### Summary of changes Bump crates to v2.1, Rust to 1.81, and use component crates wherever possible. The CPI program has a higher CU usage also, so update the README to reflect that.
