Feature/run sigv4 test suite (#58)

* Ensure asynchronous region and credential resolution is covered by tests

* Factor SJCL-based SHA-256 into its own package to all usage without requiring all browser-based implementations

* Add an HTTP message serialization/parsing library

* Add support for switching to "S3 mode" via constructor parameters (applyChecksum = true and uriEscapePath = false)

* Add official sigv4 test suite

* Add a standalone NodeJS-based SigV4 package

* Add a standalone browser-based SigV4 package

* Add a standalone universal JS SigV4 package

* Specify base when parsing HTTP status codes

* Remove extra dependencies from crypto-sha256-browser

* Ensure tests in signature-v4 are all using crypto-sha256-js
