new tests

[kushalkolar]

• @_component_indices_parser
• @cache.invalidate
• run_eval()
  • get_good_components() before and after eval
  • get_bad_components() before and after eval
• get_detrend_dfof() with diff args, such as dfof and just detrend
• get_chunked_dfof()
• get_rcm() with different temporal_components arg
• modify tests for get_rcm(), get_rcb() and get_residuals() w.r.t. the new Lazy arrays #140

Add these to an existing test function that produces a lot of rows:

• get_children()
• get_parent()
• save_to_disk() with safety checks
• remove_item()

@clewis7 easiest ones to start with are @cache.invalidate, save_to_disk() and remove_item().

get_children(), get_parent() and @_component_indices_parser() are also easy but wait until I can #119 for those.
