Merge Mondo term (ID and Label)
MONDO:0016022 'early myoclonic encephalopathy'

Into:
MONDO:0800491 'early-infantile DEE'.

Suggested revision and reasons
According to ILAE:
"Early-infantile developmental and epileptic encephalopathy syndrome (EIDEE) is characterized by frequent drug-resistant seizures that begin ≤3 months of age, with abnormal interictal EEG and neurological examination. This syndrome encompasses the previous syndromes of Ohtahara syndrome and early myoclonic encephalopathy. Treatable metabolic etiologies (especially pyridoxine and pyridoxal-5-phosphate disorders) should be excluded early."
