[WIP] [ENH] allow user to specify callosal bundles in list of bundle names for bundle_info, add example

[36000]

This allows the user to also give callosal names when using bundle_info as a list. It also adds an example where we use the api to run pyAFQ with both sets of bundles.

This is a duplicate of #538 , I have moved this example to that PR.
