Localized date fns

[tomazed]

I took a shot at doing localization with date-fns
I do not like the lines

import { de as localeDE, enUS as localeENUS, es as localeES, fr as localeFR, hr as localeHR, it as localeIT, pl as localePL, zhCN as localeZNCN } from 'date-fns/locale'
let locale = {
  de: localeDE,
  enUS: localeENUS,
  es: localeES,
  fr: localeFR,
  hr: localeHR,
  it: localeIT,
  pl: localePL,
  znCN: localeZNCN
}

from https://github.com/advplyr/audiobookshelf/blob/master/client/plugins/init.client.js

but for the love of god, I could not simply do a import locale from 'date-fns/locale' just like stated in the docs
There must be a better way, but this one works...

I also took the liberty to generate the months and weekdays through date-fns format function. I think this render

audiobookshelf/client/strings/en-us.json

Lines 630 to 643 in 5724887

	"WeekdayFri": "Fri",
	"WeekdayFriday": "Friday",
	"WeekdayMon": "Mon",
	"WeekdayMonday": "Monday",
	"WeekdaySat": "Sat",
	"WeekdaySaturday": "Saturday",
	"WeekdaySun": "Sun",
	"WeekdaySunday": "Sunday",
	"WeekdayThu": "Thu",
	"WeekdayThursday": "Thursday",
	"WeekdayTue": "Tue",
	"WeekdayTuesday": "Tuesday",
	"WeekdayWed": "Wed",
	"WeekdayWednesday": "Wednesday"

and

audiobookshelf/client/strings/en-us.json

Lines 536 to 547 in 5724887

	"MonthApr": "Apr",
	"MonthAug": "Aug",
	"MonthDec": "Dec",
	"MonthFeb": "Feb",
	"MonthJan": "Jan",
	"MonthJul": "Jul",
	"MonthJun": "Jun",
	"MonthMar": "Mar",
	"MonthMay": "May",
	"MonthNov": "Nov",
	"MonthOct": "Oct",
	"MonthSep": "Sep",

useless

having slept on in, just because it works does not mean it should be merged... there are better ways to do it, and I'm not convince putting ConfigDateFnsLocale in the strings was a good choice from a maintainabily point of view....

Let me find a better way

It's better now, I learnt to use js import 😅
@advplyr hope the code meet project coding guidelines. If you want some other clean up, telle me

This is great, thanks for taking care of that! Tested and working for all languages.
