Rename aloft bucket to `aloftdata`

[peterdesmet]

As part of updating our infrastructure for the processing and storage of European vp/vpts data, we (unfortunately) had to recreate the s3 bucket where data are stored. It now has the name aloftdata rather than aloft. This PR updates functions and tests that access the bucket (I also made some minor suggestions to NEWS.md).

Note that in the current 0.7.1 version of bioRad, list_vpts_aloft() will generate URLs of the form https://aloft.s3-eu-west-1.amazonaws.com, while this update will have the function return https://aloftdata.s3-eu-west-1.amazonaws.com URLs. The old aloft bucket will still be accessible for the next 6 months, but accessing data will be slow and new data will not be added. So it depending on use, it might be worth releasing a 0.7.2 hotfix in the coming months.

https://aloftdata.eu/browse already points to the new bucket.
