Add transform points

[HaleySchuhl]

Describe your changes
Add a function to transform a set of points given a georeferenced shapefile/geojson and a spectral data image. The points get transformed to a usable numpy coordinate system.

Waiting on update to read_geotif (switch to PlantCV-data dataclass syntax) which adds the geo_transform trait, which is a requirement for the transformation algorithm.
