Description
According to [the get_ranges docs](https://developmentseed.org/obstore/latest/api/get/#obstore.get_ranges) for the coalesce param you can "Set to 0 to disable coalescing", but in my testing this doesn't actually work if I want to download adjacent ranges in parallel.
Taking a quick look at the merge_ranges [code in arrow-rs-object-store](https://github.com/apache/arrow-rs-object-store/blob/706b7d8b536fd02a8a323bb8dbeae344fc8d65eb/src/util.rs#L158) it seems that the comparison is `<=` so I guess the documentation is wrong.
Would be nice to actually have this feature though.
