Grid prioritisation functionality bugfix

Grid prioritisation feature

Grid prioritisation enables energy to be first drawn from the grid, with the installed solar-diesel-battery system being used to supplement the community's demands at times where the grid is unavailable. This is as opposed to the standard "self-generation" operation, wherein energy is taken first from the installed solar-diesel-battery system with the minigrid being used as a backup.

Bug

A bug was identified in #54 and fixed in #55, with integration testing and further fixes introduced in #96 with a release to master being made in #106 . The bug was an error in the calculation of how energy demand is met when the grid should be supplying energy ahead of the minigrid system.
