ogr module not available for gdal v3.2

[msmith-ccom]

Issue:
When creating the environment to run Soundspeed Manager and using conda to install gdal:
conda install gdal
Installs gdal v3.2 from the conda-forge feedstock.

Running :

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'ogr'

This is related to conda-forge/gdal-feedstock#419 and OSGeo/gdal#3149
Use of :

import gdal
import ogr
import osr

Is depreciated. It is suggested that a refactor be done to use the preferred method:

from osgeo impport gdal, ogr, osr
