Title: Use the libYAML version of yaml if it's available

I've got some tests that were running _really_ slowly, and it turned out to be because vcr uses the pure-python implementation in `yaml`. However, it seems like we should be able to try to import the `libYAML` implementation and use it if it's available. It brought my tests from 22 seconds to 2.5 seconds.
