Action: Sideload Conversation

[CWolfs]

Add an action called Sideload Conversation. It will seamlessly load a conversation into the currently running conversation (no titles, no camera resets, no exit/enter conversation).

• Support resuming (or not) the parent/host conversation
• Support unrestricted depth
• Support jumping to a specific node in the sideloaded conversation
• Support conversation root conditions like vanilla when entering sideloaded conversation
• Support usage on prompt nodes and response nodes
