Enhancement: Using installed debugger post mortem

[cansarigol]

Summary

First of all, thank you all for this amazing project. I was wondering if you guys consider replacing pdb.post_mortem with a debugger package of already installed ones. This way, we can continue with the terminals we are used to.

In my mind, it is something like this:

middleware/_internal/init.py :

def get_post_mortem():
    for package in ["pdbr", "pudb", "ipdb", "pdbpp"]:
        try:
            module = __import__(package, fromlist=["post_mortem"])
            return module.post_mortem
        except ImportError:
            continue

     
    import pdb
    return pdb.post_mortem

middleware/_internal/exceptions/middleware.py :

if litestar_app.pdb_on_exception:
    from .. import get_post_mortem
    get_post_mortem()()

Not unreasonable, but I think a better approach would be to allow passing a debugger_module or post_mortem param to the app, as it's more flexible

not related but from the screen, given the reloader uses StatReload it seems you used pip install uvicorn when using uvicorn[standard] would be a little bit faster for the reload, but mainly for the http parser.
