S3 containers for heteroscedasticity diagnostics

Collections of heteroscedasticity test results returned by runHeteroTests. A hetero_test_suite is a simple named list of htest objects with additional metadata. When diagnostics are evaluated on grouped data, the returned object inherits from hetero_grouped_suite and contains one hetero_test_suite per group along with the grouping keys.

These classes are primarily useful for method dispatch (e.g. the broom tidiers and autoplot() methods). Users typically interact with the objects via generics::tidy(), generics::glance(), generics::augment() and ggplot2::autoplot().
