Updating a pretty old program to build old .schematic files

[vico93]

Hi! I have in my modpack this program that i found in the old CC forums and used since back in 1.12.2 to build .schematic files.

The program originally require the player to unzip the .schematic file (since the format have a gzip compression), place in the turtle filesystem and call it as an argument. The script then would read the blocks on the schematic and ask the player to associate each with specific turtle inventory slots.

Unfortunately since the "flattening" post-1.13 the script stopped working (even the internal structure of the .schematic remain the old one), and i'm clueless of what i need to change to make it work again (aka build very old schematics to pre-1.12 era in modern mc).

It doesnt detect the blocks present in the schematic anymore
