Title: Remember loaded variables for later inquiry

Example use case:

When running my test suite, I want to loop through all variables in .env,
and exclude them from VCR 'cassettes' with VCR's filter_sensitive_data
method. By looping through through Dotenv.loaded.keys, I can configure
this once, and no longer have to worry about environment-specific values
polluting my test fixtures.
