Streaming enhancement (#212)
* replaces file implementation with stream implementation
* remove extraneous allow
* First sign_only push
* adds tests
* adds write_cai test
* makes tests more stream like
* In memory writing writing support
* add ingredient::from_stream and from_memory
Note: doesn't validate yet:
* adds png as valid caiwriter
* improves write_cai tests
* Add validation and thumb generation
* simplifies file opening for tests
* new streaming write apis
* Remove check until we can figure out how to make this work for all cases
* JPEG writing in WASM suppport
* Return manifest and asset
* Disable part of test until we expose APIs to WASM
* Update RemoteSigner for Wasm compatibility (#193)
* Update RemoteSigner for Wasm compatibility
* Fix async path to support ingredient box hashing (#201)
Fix asyn path to support ingredient box hashing
* Fix hash algo warning in Wasm and hashing for RSA-PSS SHA-384/512
* Support for XMP streaming write and removing manifest from streams

The Rust SDK crate provides:
-* `async_signer` enables signing via asynchronous services which require `async` support.
* `file_io` enables manifest generation, signing via OpenSSL, and embedding manifests in various file formats.
* `serialize_thumbnails` includes binary thumbnail data in the [Serde](https://serde.rs/) serialization output.
* `xmp_write` enables updating XMP on embed with the `dcterms:provenance` field. (Requires [xmp_toolkit](https://crates.io/crates/xmp_toolkit).)
