Microscopope's Iris mount

### Iris holder for Amazon microscope
For consumer grade microscope to unlock the power of 100x objective lense

- Iris: [Amazon product: B0F83V9SF4](https://www.amazon.com/dp/B0F83V9SF4)
- Microsope: [Amazon Product: B0DGCX95RC](https://www.amazon.com/dp/B0DGCX95RC)

Image shows old slide with mature azotobacter cysts with 100x objective lense and 40x camera lense. Without the iris those were just blobs.

### Why?
At the objective lense 20x and above(40x, 100x), without iris, we start hitting the diffraction limits. Thus, the objective lenses are not usable unless iris is installed.

Big thanks to [Grok @xAI](https://x.com/xAI) for helping me troubleshoot the issue.
