Update nvml interface

CHANGELOG.md

@@ -30,6 +30,7 @@ project adheres to [Semantic Versioning](http://semver.org/).
 - `target_embed_source` is now more robust: it properly tracks dependencies and
   runs again whenever any of them changes
 - Expanded tests to cover the new 2D memory operations and FFT support
+- Removed the `context` from `nvml::Device` constructors
