probably not necessary inserting of the auto_mix_prep library to the requirements.txt by pipreqs

Hello together,
thank you for your nice little tool. It worked pretty well.
After the usage, I just fund the auto_mix_prep library in the requirements.txt which I did not even have installed while my repository was working correctly in my environment.

Then I had a look in your code and found the following two lines in the "mapping" - file and found the following rows 1046 and 1047:

src:atlas
src:auto_mix_prep

After a look at the pipreqs.py it seems to me like some import from the source folder inside of my repository is causing to add auto_mix_prep to the requirements.txt py pipreqs.

The deletion of the row "src:auto_mix_prep" will probably cause to add the atlas-library.

Is any of these rows necessary? Especially since src is a common name for code inside a repository. These rows will cause the auto_mix_prep to be installed uselessly in really a lot of virtual environments if I understood it correctly.

I would propose to delete these rows if there is no real reason for them.

Inspect the mapping file around rows 1046-1047 and read the source-folder handling in pipreqs.py. Reproduce the reported requirements.txt output with a repository containing a src directory, then verify that the mapping change no longer adds auto_mix_prep unnecessarily while preserving the intended atlas-library behavior.
