[Improvement] - Batch Tabletop Circulation Network Requests

[seanmhanson]

When working with the tabletop circulation app, it would be nice to be able to submit a set of check-ins and/or check-outs at one time, rather than one at a time, since network requests can be more expensive in the wilderness that is the tabletop building during high traffic. Two examples:

Checking Out

One attendee may want to check out a set of multiple games on their badge, and so it might make sense to enter all of these in one place (a modal, etc) and submit the network request at once, to save time

Checking In

Given a list of ids to check in, it might be useful to debounce the function that makes the network request so that if someone is typing in another id within a short period, it waits to see if it can combine the requests. Alternatively, there could be a UI change to allow lists of Ids with commas, etc.
