SearchPanes integration examples throw javascript errors

The two SearchPanes integration examples fail to load in Microsoft Edge and Mozilla Firefox with a "DataTables warning: table id=example - Unknown feature: searchPanes".

Affected:

• https://datatables.net/extensions/searchbuilder/examples/integration/searchPanes.html
• https://datatables.net/extensions/searchbuilder/examples/integration/searchPanesCascadeViewTotal.html

Source files:

• examples/integration/searchPanes.xml
• examples/integration/searchPanesCascadeViewTotal.xml

I was unable to verify the fix so I will not be submitting a PR but I believe the following diff fixes both pages. I built all of DataTablesSrc and SearchBuilder and ran the web server (i.e. npm run serve) and could not figure out how to get the top and left navbars to show to confirm the fix.

Start with examples/integration/searchPanes.xml and examples/integration/searchPanesCascadeViewTotal.xml, then inspect how their JavaScript libraries are loaded. Run npm run serve and open both affected integration examples in Edge or Firefox. Done means both pages load without the unknown feature: searchPanes warning.
