Comparison with other sticker pickers

• Scalar is the default integration manager in Element, which can't be self-hosted and only supports predefined sticker packs.
• Dimension is an alternate integration manager. It can be self-hosted, but it's more difficult than Maunium sticker picker.
• Maunium sticker picker is just a sticker picker rather than a full integration manager. It's much simpler than integration managers, but currently has to be set up manually per-user.
