Add method for obtaining canonical inscription ID in docs?

[arik-so]

The way the docs currently describe getting the inscription ID, it will not be deterministic due to explorers being case-insensitive and allowing leading 0s.

ord/docs/src/inscriptions.md

Line 162 in a1f0683

let inscription_id = window.location.pathname.split("/").pop();

Oftentimes, the inscription ID is used as a seed for pseudorandom outputs for generative collections, and results in inconsistencies across various viewers. Would it make sense to add a canonicalization function to the docs, such as below?

// this code is not optimized
function normalizeInscriptionId(input) {
  const m = String(input).trim().match(/^([0-9a-fA-F]{64})[iI]([0-9]+)$/);
  if (!m) throw new Error("Invalid format: expected <64-hex><i><decimal index>");

  const txid = m[1].toLowerCase();
  const index = BigInt(m[2]).toString();
  return `${txid}i${index}`;
}

Which explorers use a different formatting?

I think maybe we should just specify that the canonical encoding is lowercase with no leading zeros in the index. I'm not sure if the code helps.
