Remove unnecesary lines of code in QNT

[iturbideM]

Description

The lines of code referenced seem to serve no purpose but are being executed unnecessarily. These lines should be removed if they are indeed redundant.

pyModelExtractor/pymodelextractor/learners/observation_tree_learners/bounded_pdfa_quantization_n_ary_tree_learner.py

Lines 138 to 142 in 1f240d8

	for state in list(states.keys()).copy():
	if state not in accessed_states and states[state].initial_weight != 1:
	del states[state]

pyModelExtractor/pymodelextractor/learners/observation_tree_learners/pdfa_quantization_n_ary_tree_learner.py

Lines 210 to 212 in 1f240d8

	for state in list(states.keys()).copy():
	if state not in visited_states and states[state].initial_weight != 1:
	del states[state]

Proposed Changes
