Include MIT license in generation configuration

[philcluff]

Addresses #64.

Doesn't run a regenerate because we've got one in the pipeline, but I've run a local regeneration, which creates this change in setup.py:

diff --git a/setup.py b/setup.py
index 13ec39e..1f50724 100644
--- a/setup.py
+++ b/setup.py
@@ -44,4 +44,5 @@ setup(
     include_package_data=True,
     long_description=get_file_text("README.md"),
     long_description_content_type="text/markdown",
+    license="MIT",
 )

This will go out in the next release of the Python SDK.
