when a user requests a series or sub-series, create one transaction per container within them

sketching out a possible solution:

• on the collection page, make series and sub-series unrequestable (I think this is how the old site works)
• if a user tries to request a series or sub-series from its object page, look for all of the (objects? containers?) associated with that object and create/submit one request for each of them
  • would need to explain to the patron why we do that

I decided to turn requesting for series and sub-series off for now. might could add an alert for patrons explaining that

Requesting turned off by psuscl/request_list#1 (but we still should leave the issue open)
