ProfileCard: Crop the image to a square when selected.

[mikanIchinose]

Background

The image displayed on the profile card is intended to be shown as a circular crop.

We wanted to implement the cropping process at the time of image selection, but it is difficult to do on both platform. Therefore, in the current implementation, we display an error if the selected image is not square.

Spec

1. select an image
2. show cropping screen // <- new feature!!
3. after cropping, back to edit screen
