Add first draft backtest script

dfulu commented 5 months ago

Description

Add first draft of a backtest script. This is for running PVNet and the summation model for the UK GSP and national level predictions. Also includes some minor tidying.

[x] TODO test locally that it works

How Has This Been Tested?

This has been tested locally. I ran the script with the user variables set to the values they are set to in the script. This was two init-times and using the PVNet model and summation model which are currently on the dev branch. After running the backtest for these two init-times I checked them against the PVLive values and they seemed reasonable

To test with pytest would require a huge amount of build up and teardown to get it to work

Yea, it would be trickly to test with pytest, as you need a fair amount of fake data e.t.c. Its probably something to do in the future, but this is a great first step
