Sparse updates in batches

[imjared]

There are two issues related to this:

• https://github.com/ruckus/quickbooks-ruby/issues/152
• https://github.com/ruckus/quickbooks-ruby/issues/384

One was marked as completed and the other points to QBO API documents. The actual source of this gem leads me to believe that it's not actually possible to add sparse: true to a batch update operation since:

• batch#make_request doesn't accept a sparse option (link)
• Underlying models/entities that get passed to make_request can not be built with sparse: true as per QBO docs.

Is there a way around this?
