See timothycrosley/isort#652 for more information. tl;dr is `pip install isort==4.3.0` fails, which is what `pip install -Ur requirements.txt` will attempt to do.
Ban this specific version as it causes issues.
* Simplify command exception debugging and make stdio work correctly
* Make isort happy
* Reorganize exception handler, add default case
* Fix print statement
* Attempt to use ipdb where available
* Sort requirements and add ipdb
* Only use pwndbg.stdio in the exception handler
* Documentation, hook pdb.set_trace()
* Do not require ipdb
* Remove import loop, fix accidental call, set python print-stack
* Use the correct values for print-stack
* Use pdb.Pdb for better set_trace()
* Use Pip version of Unicorn
* Remove capstone submodule
* Allow installation to the user site-packages for Darwin, since SIP prevents installation to the system site-packages
* Add helper functions and fix Python calls
* Remove duplicated code (rebase issues?)
