pre-commit rules remove unused variables but does not delete the object assigned to the variable

pre-commit rules remove unused variables but does not delete the object assigned to that variable

During the testing process of PR #56 I discovered the pre-commit rules had deleted an unused variable but did not delete the subsequent code / object assigned to that variable. This resulted in error B018 Found useless attribute access. Either assign it to a variable or remove it.

How to reproduce

Original code lines in utilities.py:

battery_annual_energy_kwh = hopp_results["annual_energies"]["battery"]  # annual energy from battery (kWh)
battery_system_capacity_kwh = hopp_results["hybrid_plant"].battery.system_capacity_kwh  # battery rated capacity (kWh)

where the two variables were not used later in the code
run pre-commit run --file greenheart/tools/eco/utilities.py

Relevant output

greenheart/tools/eco/utilities.py:1479:5: B018 Found useless attribute access. Either assign it to a variable or remove it.
