Better organization of PO files.

This is a sample on how to use localization and perform language switching on Blazor Server by using Portable Object (PO) files. In this example we implement ILocalizationFileLocationProvider that allows us to organize our PO files better.

We will be using OrchardCore.Localization.Core package with version 1.0.0-rc1-13433.

For this example to work, you need to add additional NuGet sources using this instruction.
