  tplot/frame.py: fixes for Matplotlib 3.3+ (#1191)

* tplot/frame.py: fix for Matplotlib 3.3+

Reason: The iterable function was deprecated in Matplotlib 3.1 and will be removed in 3.3. Use np.iterable instead.

Inspired by https://github.com/stonebig/plotnine/commit/2044a91c37ba2e732fcd823fddb07cb7f5f06977

* fix set_picker deprecation warning

* remove unused cbook import
