v0.9.0

This version adds support of libsecp256k1, a pure Rust secp256k1 implementation. To use it, use the rust-secp256k1 feature to replace the default c-secp256k1 feature.

sputnikvm = { version = "0.9", default-features = false, features = ["std", "rust-secp256k1"] }

TransactionVM's real_used_gas function is renamed to used_gas and is added to the VM trait.
