bump version

This enhancement adds support for properly handling RGBA images in the tensor_paste function.

The previous implementation caused errors when pasting images with alpha channels.
Now the function can handle all combinations of RGB and RGBA images:
- RGB to RGB (unchanged)
- RGBA to RGBA (with proper alpha compositing)
- RGB to RGBA
- RGBA to RGB

Fix for the error: "RuntimeError: The size of tensor a (4) must match the size of tensor b (3) at non-singleton dimension 3"
