Update default energy rates

I see that 2024 data is available in SEDS.

I also found that EIA has an API that we should consider using.

For example, here are electricity prices from SEDS

That said, I think one of the reasons we switched to SEDS is because the data is easier to work with. But via the API, maybe we should reconsider? If we used other data sources, we could get more recent data faster. For example:

• Electricity prices (2025)
• Natural gas prices (2025 for most states)

SEDS also provides e.g. wood prices by state, so we should probably just stick with it.

So I'm thinking we create a tasks.rb task to hit the API and download the data into a CSV file (can we use this format?), and then update the OS-HPXML code to use it.
