NaN values from color scale after upgrading to v3

[aeharding]

Hello! I upgraded chroma-js and I am seeing NaN in the color output.

Example:

chroma
  .scale([
    "#0000004d",
    "#6666660e",
    "#ffffff0a",
    "#ffffff0a",
    "#6666660e",
    "#0000004d",
    "#0000004d",
    "#6666660e",
    "#ffffff0a",
    "#ffffff0a",
    "#6666660e",
    "#0000004d",
  ])
  .mode("lch")
  .domain([
    1728731361199, 1728737481199, 1728745761199, 1728759068024, 1728760868024,
    1728777068024, 1728817832257, 1728823952257, 1728832232257, 1728845367827,
    1728847167827, 1728863367827,
  ]);

Then,

console.log(colorScale(1728856800000).css()

with chroma-js 3.1.1 incorrectly returns

rgb(NaN NaN NaN / 0.19864464506172852) 

With chroma-js 2.4.2 it worked properly, returning:

rgba(43,43,43,0.19864464506172852)

✅ fixed in chroma.js v3.1.2
