add a new function node in this #93
Description
Hello, I've noticed that your open-source nodes are extremely useful. Thank you very much . referring to your program，I added two nodes to it. One is "Video Continuation Generator_V2 🎞️🅢🅜", and the other is "WAN Video Blender_V2 🅢🅜". The functions of these two nodes are not only to refer to a certain number of last frames of an input video, but also to refer to a certain number of the first frames of an another video. That is, by using these two nodes, you can refer to multiple last frames of the previous video and also multiple first frames of the next video (this is useful in video generation).You can use the "WAN Video Blender_V2 🅢" node to combine three videos together. If you think these two newly added nodes are useful, you can incorporate them into your Python program for open-source use. thanks.
