Ability to paste references to dates/daily notes

I’d like to be able to generate markup which plays nicely with daily documents when pasted into RemNote.

Current state:
If a daily document already exists I can reference it with [[2020-11-15 Sun]]. This depends on the format chosen in the settings (which it should not).
If a daily document does not exist yet and I use this syntax a new rem with the same name will be created, but it is not a #Daily Document listed under Daily Documents.

This was implemented in 1.2.1.

It only works with a specific format which can be created in JavaScript like this:

function nth(d) {
  if (d > 3 && d < 21) return 'th';
  switch (d % 10) {
    case 1:  return "st";
    case 2:  return "nd";
    case 3:  return "rd";
    default: return "th";

const month = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];

function formatDate(d) {
  return `${month[d.getMonth()]} ${d.getDate()}${nth(d.getDate())}, ${d.getFullYear()}`;

I’d like to be able to paste dates in a more easily generatable format like ISO or anything that Date.toLocaleDateString() can output. This is tracked in Further Improvements for New Rem Reference Pasting.
