Update sha2 crate to 0.9.0

As part of the update to 0.9.0, the RustCrypto suite of crates has changed some function names in their public api:
RustCrypto/traits#43
RustCrypto/hashes#157

This commit updates to the 0.9.x version of the sha2 crate from that suite and changes function calls as appropriate.
