Update model assumptions (EPC upgrade + HP installers) (#142)

* Update initial number of installers

* Update EPC requirements for HP

- BUS grant does not have insulation requirements (where as outdated RHI did).
- Assume that households still upgrade to at least EPC D when installing a HP.

* Run 10 model iterations
