Add geospatial attributes to spectral_data class

[k034b363]

Describe your changes
Some functions in the add-on packaged plantcv-geospatial benefit from having additional metadata stored as attributes of spectral_data objects. This PR adds geo_transform and geo_crs, the affine transformation matrix to convert from geo referenced coordinates to raster coordinates and the coordinate system respectively. Because they are both added with appropriate defaults (the identity matrix and "None"), this change should not affect any core plantcv functions.
