Support international weather locations

[vtnate]

Any background context you want to provide?

We were only supporting USA weather locations until now. This PR enables any location from www.energyplus.net/weather to be used (as of Sep 4, 2024). Major caveat: This only accepts *.mos weather files, which as of now are only available on the website for USA locations. Once mos weather files for all locations on the website are available, this code is ready to take advantage.

What does this PR accomplish?

• Handle all locations provided by https://energyplus.net/weather. Requires a weather file in *.mos format to be avaailable from that website, which as of today is limited to USA locations.
• Adds tests for this using the CLI and using the code directly

How should this be manually tested?

Provide a valid weather epw filename for any location outside the USA in your geojson file. Observe that the EPW is downloaded correctly and an error is raised if the mos format file isn't found.

nicely done--looks like we should have handled this from the beginning. Thanks for updating!
