I have 3 coordinates, `moving_points`

. I know where each of these is supposed to really be, `fixed_points`

. I want to transform them (and many other coordinates) to these known locations (involving translation, rotation, but also a bit of stretching).

How can I create a transformation so that when it’s applied to these 3 coordinates they become a set of known other coordinates?

MWE:

```
fixed_points = [[0,0], [0,50], [130,50]]
moving_points = [rand(2) for _ in 1:3]
trans = # Probably something involving CoordinateTransformations, the fixed_points, and moving_points
@assert fixed_points ≈ trans(moving_points)
```
