/**
 * Yoruba (Nigeria) language converter
 *
 * CLDR: yo-NG | Yoruba as used in Nigeria
 *
 * Yoruba uses a complex vigesimal (base-20) system with:
 * - Additive patterns: 1-4 added to decade (lé = "plus")
 * - Subtractive patterns: 5-9 subtracted from next decade (dín = "minus")
 * - Odd decades (30,50,70,90) formed by subtracting 10 from next even decade
 * - Even decades (20,40,60,80,100) are multiples of 20
 *
 * Examples:
 * - 21 = ọ̀kan lé lógún (1 + 20)
 * - 15 = àrùndínlógún (20 - 5)
 * - 50 = àádọ́ta (60 - 10)
 * - 45 = àrùndínláàádọ́ta (50 - 5)
