TODO:
    - Implement support for hollow roots in nif`al.
    - Implement support for geminate roots in pa`al and nif`al.
    - Implement smarter ktiv male spellings.
    - Implement support for mixed binyanim (such as for ניגש and יכול).
    - Implement support for alternative forms.

Reference:

    Input parameters:
        1: binyan abbreviation
        p: first root letter
        a: second root letter
        l: third root letter

    Root letters may be prefixed with ':' to include them literally, in which case they will not be
    parsed as hollow or weak and no dageshes will be added to or removed from them. Any of the
    final form codes or intermediate data below can also be given explicitly in the input.

    Binyan abbreviations:
        pa: pa`al
        pi: pi`el
        po: po`el/polel
        pu: pu`al
        poal: po`al/polal
        hif: hif`il
        huf: huf`al
        nif: nif`al
        hit: hitpa`el
        hitpo: hitpo`el/hitpolel
        hitpu: hitpu`al *rare modern coinage

    Tense abbreviations:
        inf: to-infinitive
        imp: imperative
        fut: future (a.k.a. imperfect or prefix conjugation)
        pres: present (a.k.a. active participle)
        past: past (a.k.a. perfect or suffix conjugation)
        noun: action noun
        pp: passive participle

    Gender abbreviations:
        s: singular *first person only
        p: plural *first person only
        ms: masculine singular
        fs: feminine singular
        mp: masculine plural
        fp: feminine plural

    Person abbreviations:
        1: first person
        2: second person
        3: third person
