append file names to state when given file name.

Test Plan and Hands on Testing

run the following protocol and make sure the files appear in the run log.

from typing import cast
from opentrons import protocol_api
from opentrons.protocol_api.module_contexts import AbsorbanceReaderContext

# metadata
metadata = {
    'protocolName': 'Absorbance Reader Demo',
    'author': 'Platform Expansion',
}

requirements = {
    "robotType": "Flex",
    "apiLevel": "2.21",
}

# protocol run function
def run(protocol: protocol_api.ProtocolContext):
    mod = cast(AbsorbanceReaderContext, protocol.load_module("absorbanceReaderV1", "D3"))
    plate = protocol.load_labware("nest_96_wellplate_200ul_flat", "C2")

    # Initialize to a single wavelength with reference wavelength
    mod.close_lid()
    mod.initialize('multi', [600, 450])

    # Remove the Plate Reader lid and move labware into the module.
    mod.open_lid()
    protocol.move_labware(plate, mod, use_gripper=True)
    mod.close_lid()

    # Take a reading and save to csv
    mod.read(export_filename="plate_reader_csv.csv")

Makes sense to me!

this will assign every measurement iteration, we should pull this out of the for loop so assignment happens once.
