* Based on the latest Bled, which adds ztsd compression support.
* Note that initial extraction of the 512 bytes MBR is very slow, because is seems
clear that ZSTD was never designed for fast init or processing small elements of
data, but instead for post init large volume streaming.
* Also note that this code adds 400 KB to the Rufus executable *AFTER UPX COMPRESSION*!
Hopefully, the BusyBox folks can come up with a better and smaller way to add zstd
support, because it's clear that the method used by the current BusyBox proposal,
which is to leave as much of the original code untouched, isn't for the best...
* Closes#2590.
* Closes#2620.
* Closes#2621.
* This adds ZIP64 support, which is required to extract zip archives that are larger than 4GB.
* Closes#2264
* Also fix a MinGW warning in pki.c and improve the UEFI revocation messages.
* Since we have compression available through Bled we might as well use it
* Also validate that the download URL comes from https://github.com/pbatard/Fido
* Also prevent the check for update from running while we are downloading ISOs
* Check compressed DD images for boot capability
* Add DisableLGP setting
* Silence libcdio errors when scanning non ISO images
* Ensure UI displays "No image selected" when relevant
* Also update Bled to latest
