Pi Zero 2 W Palmtop

This project is a remix of the tagged "Mini Raspberry Pi Handheld Notebook" Project with a few particular goals in mind

* Compatibility with the 2.8" Adafruit SKU 2298 screen - I had one of these on hand, and I don't like having spare parts floating about
* Rigidity - the original design (at least for me) needed a bit more strength; this is a design I intend to eventually iterate on but this is a basis where I wanted to begin with something that feels solid and usable. Also more material around screw/anchor points for repeat assembly and disassembly.
* Simplicity - I wasn't a huge fan of the original designs' method of sending the battery between the pi and the screen, nor anything involving bending GPIO pins
* Size - The original design incorporates one of the larger format Pi models, and I wanted to try (and did) shave off some of the vertical height; roughly a third. I'm a big fan of Palmtops, and when this one goes to valhalla I will iterate and go thinner, again, probably with a
