Feature Request - String/Hex Encoding

[Yelf42]

Hi!

Your nonogram maker is easily the best I've seen online, especially for also taking solvability into account.
I'm working on a Minecraft plugin that creates nonograms in game that can already create random nonograms (with either unique or multiple solutions), but it also supports creating nonograms from a hexadecimal representation so that identical nonograms or custom made nonograms can be created.

I've got a very thrown together method right now for getting custom made encodings, but it's cumbersome and not viable long term, so I was wondering if you could add a nonogram-to-hex conversion to your site. My bootleg approach already requires generating a json using your generator so I've already got code that converts it:

function encodeGrid(grid) {
  const height = grid.length;
  const width = grid[0].length;
  let bits = 0n;
  for (let row = 0; row < height; row++) {
    for (let col = 0; col < width; col++) {
      if (grid[row][col] === 1) {
        bits |= (1n << BigInt(row * width + col));
      }
    }
  }
  return bits.toString(16);
}

No worries if not, and thanks for the site!
