List-Ignored - tests ignored models for invalid URLs

<#
  List-Ignored.ps1 -file <file.json> [-delay <seconds>]

  Where: file.json = CTBRec config file, (usually ctbrec.json or server.json)
         seconds   = Delay between each Web Request, (avoid possible error 503), valid range 0.1-90

  example: List-Ignored.ps1 -file server.json
           List-Ignored.ps1 -file ctbrec.json -delay 3

  List ignored models with pages that don't resolve, (error 404, etc), or CB models that are banned.

  Output will be to Ignored-Model-Status.txt in the same dir as List-Ignored.ps1.
  File will be overwritten in consecutive runs.

  Tested on PowerShell 7, Windows 10 and DietPi 6.33.3, (RasPi).

  *** NOTE: Only tested with a few models on CB because I only monitor 1-3 models there, so if
            no-one tells me anything I'll assume it works on all sites.
