Minor update. The primary update was to rewrite how the over-damped ode.SolveUnc integrator coefficients are computed. Previously, high damping could cause an overflow issue because of the use of cosh & sinh functions.

A small update, primarily to cla.DR_Def.add:
- update handling of "drfunc" checks and improve error messages
- change some SRS defaults (srsopts and srsconv)

Minor update:

- add scale_by_Q_only to srs.srs_frf
- update cla tools DR_Def and DR_Results to be able to accommodate more flexible SRS options

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
