💸 Icon Picker - Bundle size too large

[Calinator444]

Description
As per Isaac's comment, we've added an icon picker for the new consulting pages. However, this component increases the website's bundle size because it imports the entire library for React Icons Box Icons.

Proposed solution
We have 3 options here:

• Choose a less expensive different icon library (i.e. one that uses CSS)
• Implement an endpoint for incrementally fetching the icons from react icons
• Find a way to only dynamically import the icons that we need to reduce our page bundle size (still unsure why the bundle for the Tina editor is included in the home page).
