Add marine infrastructure dataset and model config

[favyen2]

This adds dataset/model configs for solar farm and wind turbine models, along with corresponding inference pipelines.

It also:

• Moves convert_satlas_webmercator_to_rslearn to one_off_projects since it's no longer needed now that the conversion of the datasets (from old format + WebMercator projection to new rslearn format + UTM projection) is completed.
• Adds rslp.common.worker system to launch workers that read tasks from a queue (Google Pub/Sub topic) and execute them. In the future all task systems (like Landsat and Sentinel-2 job launchers) should be converted to this system so that they can share the same way to execute workers -- then the individual projects just need to implement the process of writing tasks to the topic.

Changing back to draft, I'm going to add the work on deploying the prediction pipeline on Beaker here.
