DiceFold update and A4 size!

I got some great feedback about how to make DiceFold better, and uploaded a US Letter and A4 version with the date 8-17-2025.

Instead of just an even distribution of dice values for each "page" - I split each of those panels into 4 quadrants, and made sure there was an even distribution of values within each quadrant. I also squished (the technical term) the numbers together to fit more, and also easier to use the B.A.R.D. system with. Lastly, I made the top-right number represent the dice type in bold and a box around it. For example, the d8 page has "8" in the top-right etc.

This is also the first version to have A4 size! Sorry, took me way longer to get around to that.
