/**
 * Applies a case to a source name provided in the nominative
 * case (nefnifall).
 *
 * @example
 * ```tsx
 * applyCase("ef", "Jóhann");
 * //=> "Jóhannesar"
 *
 * applyCase("þgf", "Helga Fríða Smáradóttir");
 * //=> "Helgu Fríðu Smáradóttur"
 * ```
 *
 * The name provided must be an Icelandic name in the nominative case
 * (nefnifall). Otherwise, an unexpected output is likely.
 *
 * The supported cases are:
 *
 * - Nominative `nom` (nefnifall `nf` in Icelandic)
 * - Accusative `acc` (þolfall `þf` in Icelandic)
 * - Dative `dat` (þágufall `þgf` in Icelandic)
 * - Genitive `gen` (eignarfall `ef` in Icelandic)
 *
 * Note that superfluous whitespace is not retained:
 *
 * @example
 * ```tsx
 * applyCase("þf", "  \n  Hildigerður  Oddný\tPatreksdóttir  \n\n");
 * //=> "Hildigerði Oddnýju Patreksdóttur"
 * ```
 *
 * @param name - An Icelandic name in the nominative case (nefnifall)
 * @param caseStr - The case to apply to the name to, e.g. `þf`
