Hi,

Pushed as e8d9a163be..12455b3634 to master. 

- [X] [PATCH 1/2] gnu: Add python-monthdelta.
- [X] [PATCH 2/2] gnu: Add python-heatwave.
  - Rephrase synosis
  - Indent as a list for propagated inputs
  - Move to version-control
  - Rename to just heatwave as it looks like just an executible not a Python library
