Foundry Arbitrary Pool Dice Roller

I roll a lot of arbitrary sets of dice and use Foundry, so I want a system that lets me roll a number of Hunger and non-Hunger dice that I choose. This macro just feeds into the Foundry World of Darkness 5e system I already have installed. To use it, just create a Macro and paste this as the code. This was mostly written by Gemini and tweaked a bit by me.

/**

 * V5 Prompted Roll Macro (Vampire: The Masquerade 5th Edition)

 *

 * This script displays a dialog box prompting the user for the number of

 * regular 'Vampire Dice' (dv) and 'Hunger Dice' (dg).

 * It then constructs the V5-specific roll formula (e.g., 4dv + 2dg) and

 * executes it by directly passing the command string to Foundry's chat processor,

 * ensuring the V5 system module correctly processes the roll result.
