Add bladeStiffenedShell constitutive model (#212)

* Add __init__ method to BaseUI

* Modify problem classes to use __init__ from BaseUI

* Starting to add a blade-stiffened shell constitutive model

* Finally figured out the math for the general stiffness matrix case

* Added stiffener stiffness calculation

* Implemented stiffener failure calculation (no buckling yet)

* Added python interface and fix some complex-mode errors

* Unit tests working (but not passing)

* `evalFailureStrainSens` works

* Reordered DVs, panelFailureDVSens working

* `addFailureDVSens` works! (no buckling yet)

* Bug fixes in stress/stiffness calculation, stress derivatives are still way off

* Finally, the stiffener pitch part of `addStressDVSens` works

* `addPanelStressDVSens` working

* FINALLY! `addStressDVSens` works

* Pushing example/test

* debugging

* Remove a bunch of incorrect inlining

* Local panel buckling works (including derivatives)

* Make the strains used in the constitutive unit tests more realistic

* Global buckling failure criteria and all derivatives work

* Remove print statement

* Fix segfault

* Update gitignore

* Remove test script

* Modify Tsai-Wu failure to work with safety factors

* Modify Tsai-Wu failure to work with safety factors

* Switch buckling envelope to safety-factor valid form

* Update integration tests with new failure values

* black .

* Remove commented out code and add comments explaining new Tsai-Wu calculation

* Add back old Tsai-Wu failure index, add method to switch between the two forms

* Increase number of extra output quantities available for shell elements so we can write out all the BladeStiffenedShell DVs

* Add panel length constraint class

* Add `createPanelLengthConstraint` to pytacs

* Minor fix

* Improve the blade stiffened shell docstring

* Remove defunct bladeFSDT code

* Add numba dependency

* `black .`

* Correct docstring for `createPanelLengthConstraint`

* Add numba to conda dependencies

* Make FD step smaller to fix failure sens failures

* Fix bug in rectangular beam Von Mises sens

* Add implementation of `assert_allclose`

* Switch to `TacsAssertAllClose` for failure criteria sens tests

* Fix `TacsAssertAllClose`

* Add abs error printout to `TacsPrintErrorComponents`

* Switch to `TacsAssertAllClose` for all constitutive tests

* Fix some array initialization bugs

* Fix some more initialization bugs

* Tighten tolerances for constitutive tests

* Squashed commit of the following:
