Infeasible UC model when including forecast error scenarios about asosepoc HOT 4 CLOSED

Ideas to try:

* Selectively remove scenarios

* Reduce reserve coverage

* Only consider upwards or downwards reserves

from asosepoc.

Reducing the number of scenarios by 400 (2*200) fixes things.

More investigation has revealed the following for day 5:

• Despite constant load shedding and the possibility of shedding reserves, reserve shedding is limited mostly to certain parts of the day (seemingly when there's solar?)
• in timesteps 10 and 11, the overall net load forecast error is +ve, leading to negative values of D-. I'm actually very surprised that this didn't lead to infeasibilities... I prevented this from occurring using commit fb3939a

from asosepoc.

There was no error because I had mistaken D+ with D-, hence D- was not being used. Fixed by b0eeb1d.

Since no more infeasabilities, I'm considering this issue closed, though I'm sure there's more issues with my model.
