Context

When deploying a Django app (over 50mb) from a Windows 10 machine the tarball retains the Windows directory separators '\\', when deployed to Lambda this causes the error "No module named 'django.core.wsgi': ModuleNotFoundError"

Expected Behavior

1. tarball should keep Unix directory separators

Actual Behavior

1. tarball retains Windows directory separators

Possible Fix

In core.py, line 683 can be replaced with:

tarinfo = tarfile.TarInfo(posixpath.join(root.replace(temp_project_path, '').lstrip(os.sep).replace('\\', '/'), filename))

Which fixed it for me but is quite hacky and probably not that robust.

Steps to Reproduce

1.zappa deploy dev on Windows 10 machine with app over 50mb
