Minor update. Added cla.DR_Results.delete_data: a more powerful version of cla.DR_Results.strip_hists.

Updates focused on the cla.DR_Results class. It's not strictly backward-compatible due to the iterator updates; see notes below.

- add legend_args to cla.DR_Results.srs_plots and .resp_plots routines
- allows user to control display of legend
- add "verbose" option to the cla.DR_Results data recovery functions
- time_data_recovery, frf_data_recovery, and psd_data_recovery
- add path output to cla.DR_Results iterators:
- all_base_events
- all_nonbase_events
- all_categories

Pretty minor update overall:
- nastran.bulk.asm2uset now reads the EXTRN card from the .pch file for EXTSEOUT type models
- it can now handle b-set nodes that do not include all 6 DOF
- in nastran.n2p.mkdofpv / nastran.n2p.expanddof: add "grids_only" and modified "strict" usage for more versatility
- some doc updates

- updated psd.psd2time:
- non-backwards compatible change!
- ppc & df now optional
- reorder input
- improve documentation

- improved speed of ODE static ic computation
- many thanks Jeremy Priest for this one! :)

- enhanced nastran.n2p.mkdofpv, nastran.n2p.expanddof:
- 1d array dof can have ids of non-grids too

- other miscellaneous improvements

- make compatible with scipy >= 1.8
- various updates to plotting in cla
- update logic and options for the "magpct" plots
- avoid using matplotlib.pyplot unless showing plots on screen
- add ytools.max_complex_vector_sum
- compute maximum complex vector from x and y components
- miscellaneous docstring updates & bug fixes

Minor update, primarily to add ytools.max_complex_vector_sum.
