Description of Changes

This PR adds the ability to reload pwncat modules at runtime. This is facilitated through the addition of a new flag for theManager.load_modules method, which now takes aforce keyword argument, which forces reloading of previously loaded modules. Further, there is now a newManager.reload_module method which accepts either a module instance or a module name to be reloaded specifically. Bothload_modules andreload_module methods will also attempt to fix the current module context if a module is being reloaded, and reset any module configurations, which could fail if the module arguments have changed during reload. If a module-specific configuration fails to apply after reloading the module (likely because the module arguments changed on disk), a warning is printed and that configuration is lost.

Lastly, this PR adds new arguments to two pwncat commands:load andrun. First, theload command now as either--force/-f or--reload/-r arguments. These are synonyms which force a reload of modules during loading (through the force argument ofManager.load_modules). Second, therun command now accepts a--reload/-r argument which forces the selected module to be reloaded viaManager.reload_module prior to execution, which should be useful when debugging a new module (or a misbehaving old module).

Fixes#241.

Please note anynoqa: comments needed to appease flake8.
