In support of a domain code review, fix spelling errors

To support a domain code review, this commit largely addresses minor spelling issues in the code's comments. There are a few exceptions listed below.

- ale\base\type_sensor.py : typo fixed in the code line [181](https://github.com/USGS-Astrogeology/ale/blob/ce3a77cb5fb5749bbc67e0e8bd8a82235cb395c5/ale/base/type_sensor.py#L181)
- ale\drivers\co_drivers.py : apparent value typo in line [75](https://github.com/USGS-Astrogeology/ale/blob/ce3a77cb5fb5749bbc67e0e8bd8a82235cb395c5/ale/drivers/co_drivers.py#L75). please validate update.
- ale\util.py : internal only to the script, the function named "case_sensative" was updated to correct misspelling
- tests\pytests\test_cassini_drivers.py : internal only to the script (and test_util.py), the function named "read_detatched_table" was updated to correct misspelling
- tests\pytests\test_lro_drivers.py : unnecessary semicolon was removed.
- tests\pytests\test_util.py see _test_cassini_drivers.py_ for same update above.
