Add flexibility for object/initializer that is used for adding/updating copy in culture file

[brandongregoryscott]

Right now, the logic that finds the 'resources' object to insert or update key/values in is pretty tied to the structure in the README (ie, the literal initializer that is passed to LocalizationUtils.cultureFactory(...)

On a client project that this extension was primarily based off of, we recently got the first professionally translated file back and had to import the data. In an effort to keep future translation files smaller (sending over only the new or updated copy), we moved all of the keys and values that had changed into another object above the literal object that is passed to LocalizationUtils.cultureFactory(...).

This issue should investigate ways to ease the specificity of which object is pulled for inserting/updating keys. Perhaps the first literal object that has the key (if updating) or the last literal object (if adding). There may be an opportunity for a configuration setting to add control for this, too, though I'm not sure there's a use case other than the one described.

Example:

import { BaseSpanishSpain, Culture } from "andculturecode-javascript-core";
import CultureResources from "utilities/interfaces/culture-resources";
import LocalizationUtils from "utilities/localization-utils";

const ProfessionallyTranslatedSpanishSpain = {
    "aboutApp": "Acerca de {{appName}}",
    "acceptGroupInvitation-invitedByNameToJoin": "{{byName}} te invitó {{toJoin}}",
    "acceptGroupInvitation-invitedToJoin": "Has sido invitado {{toJoin}}",
    // ...
    "warnings-thisActionCannotBeUndone": "Esta acción no se puede deshacer.",
    "yellow": "Amarillo",
    "yesAction": "Sí, {{action}}",
    "you": "Tú",
    "yourItem": "Su {{item}}",
};

const SpanishSpain: Culture<CultureResources> = LocalizationUtils.cultureFactory(BaseSpanishSpain, {
    resources: {
        ...ProfessionallyTranslatedSpanishSpain,
        "admin": "Administración",
        "all": "todas",
        "allOfItem": "Todo {{item}}",
        "clearAll": "Limpiar todo",
        // ...

});

export default SpanishSpain;
