add type descriptions for complex input

[automaticgiant]

Description

attempt describing datasources input with complex type

it's my first time using these, and i'm also not 100% sure it captures everything about the module. just hoping to move the bar a little bit.

Motivation and Context

unclear what options are supported for data sources; caused #64 to be made then closed. documentation followup.

Breaking Changes

none
