Updated app icon

[declan-wade]

Summary

This to update the app icon to incorporate the new branding recently announced. Similar to a recently merged PR in the Android repo, refer here: home-assistant/android#3888. I note that the new icon when used on dark backgrounds is not white, it is a very light grey, as per the branding guidelines.

Refer to screenshot below to compare with the existing (icon 2 is the selected icon), below is an explanation of the options.
The image dimensions match the existing format.

Screenshots

1 -- App icon matches almost exactly the android app. Seems too small, as Android icons (i.e. Pixel Launcher) are cropped to a circle, rather than iOS which just rounds the corners with a set radius.

2 -- App icon matches the existing iOS icon in size and position. This is not actually perfectly centered on the canvas, it is offset slightly on the Y-axis to be slightly higher and gives the illusion it is centered. This looks the most visually pleasing.

3 -- Current icon

4 -- App icon is perfectly centered and scaled to encompass the existing iOS icon, which results in it looking a bit too big and gives the illusion the icon sits slightly too low on the canvas.
