feat: restore automated Windows .iso downloads from Microsoft servers
This implementation is based on Mido: - https://github.com/ElliotKillick/Mido More useful failure messages are presented and if the download is blocked clear steps to manually complete the setup are presented. Windows 8 is re-instated as a supported release, although without install automation or driver optimisation.

# For testing Fido, replace all "https://" with "http://" and remove all instances of "-MaximumRedirection 0" (to allow redirection of HTTP traffic to HTTPS) so HTTP requests can easily be inspected in Wireshark
|

# Fido (command-line only) works under PowerShell for Linux if that makes it easier for you
|

# UPDATE: Fido v1.4.2+ no longer works without being edited on Linux due to these issues on the Fido GitHub repo (and possibly others after these): #56 and #58
|

#

# If this function in Mido fails to work for you then please test with the Fido script before creating an issue because we basically just copy what Fido does exactly:
