New feature

- omero.gateway: add new `getObjectsByMapAnnotations` API
[285](https://github.com/ome/omero-py/pull/285)
- CLI: Add support for downloading fileset and multi-file images [298](https://github.com/ome/omero-py/pull/298)

The CLI feature also introduces a backwards-incompatible layout change for
the download of images to mitigate the risk of data corruption associated with
renaming files. The command now specifies a directory path under which all
files associated with the image are downloaded using the original file names
and structure.

Bug Fix

- CLI: point users at [image.sc](https://forum.image.sc/) for reporting bugs
