Can you bump the version of lap to 0.5.13

In your `requirements.txt`, the verson of `lap==0.4` is too old. It causes a lot of issue these days. For example, my python version is `3.10` and I cannot install `lap==0.4` with it. Thanks!

Open requirements.txt and locate the lap==0.4 dependency. Check the requested 0.5.13 release and Python 3.10 compatibility, then verify that the updated requirements install successfully; done means requirements.txt uses lap==0.5.13 without breaking installation.
