Expand InsertBulkOptions

[tbasallo]

You can tell I've been doing a lot of work with SqlBulkCopy (in Azure Functions).

Any thoughts on expanding NPoco.InsertBulkOptions to allow options/settings to be used in generating and executing the SqlBulkCopy?

Some of the items that would be useful to pass in:

• Batch size
• Table name #647
• Enable streaming

While we're at it, I could include a column mapping, as well. But not as important.
