Feature request - pull IPSW files for macOS

[carlashley]

With the new Apple Silicon systems, IPSW files can be used in Apple Configurator to lay down a new macOS 11+ OS on a Mac.

Could the ability to pull these IPSW files be added to mist?

For the IPSW's, it seems like the server supports resume and will return HTTP status 412 if the file was updated server side, and HTTP status 416 if the download is complete.

Creeping up on parameter / flag naming collisions, so the commands have been reworked slightly:

• mist --list is now mist list
• mist --download is now mist download
• mist --version is now mist version
• mist list --platform apple for Apple Silicon IPSW files
• mist list --platform intel for Intel Application bundles
• mist download --platform apple --firmware-name "Custom Name" to specify a custom filename
