Some FPGA_dev

Some things for me to remember:

• Start new project by making new folder and copying over from Makefile, ice40.pcf, top.sv
• Build with make and deploy it to the pico-ice with make prog, and make gateware.uf2 to generate an uf2 image to program with drag-and-drop.
• If you drag and drop the .uf2 Mac osx Sonoma will pop up with "The Finder can’t complete the operation because some data in “gateware.uf2” can’t be read or written. (Error code -36)" This can be ignored and the pico-ice fpga should be flashed.
