JAPANESE_SOUND_GEMINATION_CHANCE_NUCLEUS	How likely the nucleus (vowel) is to geminate ie a -> aa
JAPANESE_SOUND_GEMINATION_CHANCE_INITIAL	How likely the initial (consonant) is to geminate ie k -> kk
JAPANESE_SOUND_PALATALISATION_CHANCE	How likely the consonant is to palatalise ie r -> ry
JAPANESE_SOUND_NULL_INITIAL_CHANCE	How likely the syllable is not to have a consonant at the start, needs to be kinda high for convincing diphthongs
JAPANESE_SOUND_N_FINAL_CHANCE	How likely the syllable is to end in an N
JAPANESE_SOUND_APOSTROPHE_CHANCE	How likely it is to insert an apostrophe between two syllables (this can happen anywhere, mainly used for morpheme boundaries.)
JAPANESE_SOUND_GEMINATION_CHANCE_VOICED	how likely voiced sounds are to geminate, these mainly occur in foreign loans so quite unlikely
/datum/japanese_syllable	holds the syllable's sound itself and information such as if it has a null initial or final_syllable
/datum/japanese_sound	a generic sound
/datum/japanese_sound/initial	an initial sound aka a consonant, contains a lot of data about stuff that only consonants can be
/datum/japanese_sound/nucleus	a nucleus, aka a vowel sound
/datum/japanese_sound/final_syllable	a final_syllable sound, not used for much since the only one possible is N.
