NanoEventsFactory.from_parquet triggers a TypeError in delayed mode when events is called

[NJManganelli]

Describe the bug
calling events() on NanoEventsFactory.from_parquet(filename, delayed=False) works okay, but with `delayed=True,' it triggers an unexpected code path/error:

To Reproduce

# with coffea.__version__ == '2024.1.2'
import coffea
from coffea.nanoevents import NanoEventsFactory, NanoAODSchema
fname = "/afs/cern.ch/user/n/nmangane/public/part00.parquet"
pqe = NanoEventsFactory.from_parquet(fname, delayed=False)
pqe.events().fields
#output:['FatJet', 'L1Reco', 'SoftActivityJetHT5', 'SoftActivityJetHT10', 'Flag', 'LHEPart', 'SoftActivityJetNjets10', 'OtherPV', 'luminosityBlock', 'Jet', 'genWeight', 'PSWeight', 'fixedGridRhoFastjetCentralCalo', 'GenMET', 'HTXS', 'GenDressedLepton', 'SoftActivityJetNjets2', 'PV', 'SV', 'Muon', 'SoftActivityJetHT', 'fixedGridRhoFastjetCentralNeutral', 'L1simulation', 'PuppiMET', 'btagWeight', 'genTtbarId', 'GenJetAK8', 'HLTriggerFinalPath', 'DeepMETResponseTune', 'FsrPhoton', 'fixedGridRhoFastjetCentral', 'fixedGridRhoFastjetAll', 'Pileup', 'SoftActivityJetNjets5', 'LHEReweightingWeight', 'HLTriggerFirstPath', 'LHEPdfWeight', 'HLT', 'Generator', 'GenPart', 'RawMET', 'RawPuppiMET', 'Photon', 'MET', 'event', 'fixedGridRhoFastjetCentralChargedPileUp', 'CorrT1METJet', 'DeepMETResolutionTune', 'Tau', 'CaloMET', 'LHEScaleWeight', 'run', 'ChsMET', 'GenJet', 'LHEWeight', 'SoftActivityJetHT2', 'GenIsolatedPhoton', 'TkMET', 'GenVisTau', 'Electron', 'SoftActivityJet', 'LHE']
pqd = NanoEventsFactory.from_parquet(fname, delayed=True)
pqd.events()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/srv/.env/lib/python3.11/site-packages/coffea/nanoevents/factory.py", line 674, in events
    events = self._mapping(form_mapping=self._schema)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: from_parquet() got an unexpected keyword argument 'form_mapping'

Expected behavior
Produced form_mapped dask-awkward array

This is not yet supported in coffea 2023. Form remapping needs to be implemented for dak.from_parquet. Only root input is available at present in delayed mode.
