Update AEMO dataset to get new DUIDs

[kvw99]

Re: customer support ticket #517 - a customer reported energy data in the dataset "Current Power Generation - NEM, All generation types" not being updated due to a DUID change from AEMO:

"VBBL1 has not received data since October on this map, I believe due to this issue – the DUID has changed from AEMO... the summary is they changed the DUID column of the NEMweb DISPATCH_UNIT_SCADA release (in a seemingly inconsistent way) meaning existing maps must be updated."

As a result we need to run an update for NationaMap to get the new DUIDs.

Please advise @kvw99 when complete so that I can test and update the customer.

Looking at this now.

As I mentioned in standup, the sheet name our parser looks for has changed in the new spreadsheet. It has changed from Generators and Scheduled Loads to PU and Scheduled Loads. Not sure how long it has been, but that means we might have been missing out on new stations for a while.

I'll try and update this, plus there are a few other issues with the new sheet that needs fixing (like for eg some values have a new line in them which breaks our parser)

@na9da does this link to any PR/s?

@na9da I think this is done

This is fixed, here's data for the new VBB1 storage unit - https://nationalmap.gov.au/#share=s-dWusp4qWt6lrVWjynKB0YzFJ3ww

need that old DUIDs will still show up on the map (for now).
