Alpha v0.17.1

NOTE: As a reminder, the windows installer still does not open after installing anymore. It still does install though, so just manually open it after installation. We are actively investigating why this happened.

This update includes some new nodes, a quality-of-life improvement related to stopping execution, even more portability, and a bit more. See the full changelog below:

Minor Changes

• Long-running upscales can now be stopped, without chaiNNer seeming to hang (#1521)
• Added DDS option for separating alpha (#1510)
• Slight styling changes for slider input numbers (#1504)

New Nodes

• Random Number (#1499, thanks @Zarxrax)
  • Allows using a randomly generated number for number inputs
• NCNN Model File Iterator
  • Similar to the PyTorch model file iterator, these allow you to iterate over folders of NCNN models.
• ONNX Model File Iterator
  • Ditto above, but for ONNX
• Lens Blur (#1516, thanks @harisreedhar)
  • Applies lens blur to an image

Bug Fixes

• Fixed RGBA DDS loading (#1514)
• Fixed chaiNNer closing when visiting the update link, or dismissing the box (#1518)
• Fixed some missing portability when using a portable zip (#1523, #1530)

And of course, thanks @joeyballentine and @RunDevelopment
