Capture tile sort order during bulk import

[johnatawnclementawn]

For cardinality-n cards, tiles can be sorted at the card level for a given resource. This is important for things like resource descriptors which derive the resource display name from the tile with the lowest sort order if using a cardinality-n card.

Currently, the Bulk Data Manager import modules do not have a way of explicitly controlling the tile sort order for tiles being imported. The current behavior is to initialize tiles with a sort order of 0, and leave any sorting to the front end (if any).

The primary goal should be to enable the ability to control sort order while creating new tiles through the bulk data importers. There should be discussion around how to handle new tiles that are not explicitly given a sort order provided in the imported csv/excel.
