<#
    .SYNOPSIS
        Imports a set of localized strings from a PowerShell data file.
     
    .DESCRIPTION
        Imports a set of localized strings from a PowerShell data file.
        This is used to feed the localized string feature set.
        Always import for all languages, do not select by current language - the system handles language selection.
     
        Strings are process wide, so loading additional languages can be offloaded into a background task.
     
    .PARAMETER Path
        The path to the psd1 file to import as strings file.
     
    .PARAMETER Module
        The module for which to import the strings.
     
    .PARAMETER Language
        The language of the specific strings file.
        Defaults to en-US.
     
    .EXAMPLE
        PS C:\> Import-PSFLocalizedString -Path '$moduleRoot\strings.psd1' -Module 'MyModule'
     
        Imports the strings stored in strings.psd1 for the module MyModule as 'en-US' language strings.
