Batch adding of data to the library

[tjkuson]

Describe the solution you would like
The ability to add multiple scans to the library in one operation.

Describe alternatives you have considered
Currently, only one scan can be added at a time. This works, but is a bit slow if you want to add multiple scans or projects.

Additional context
In terms of behind-the-scenes finding-and-adding of data, this is pretty easy. However, this might be a bit difficult from a user interface perspective. Currently, the user selects one scan, its format, and then views the metadata and adds it manually. Selecting, say, ten scans at once presents a few issues:

• What if they are not, for example, all the same format?
• How do we present the scan information to the user? If we show it all, that can be graphically overwhelming to the user. If we don't show all of the scan information, then that means the user cannot validate what it is they are adding. Neither seems optimal.
