Update node-minecraft-data dependency

[bluetidepro]

In package.json (https://github.com/1b8/schematic/blob/master/package.json#L18) it looks like schematic is only using ^0.14.0 for minecraft-data.

https://github.com/PrismarineJS/node-minecraft-data is on version 0.17.0. Would it be a good idea to update this dependency version to get newer block data?

I thought that since it had the ^ before the 0.14.0 it would still actual download 0.17.0, but it doesn't seem to do that. My node_modules has minecraft-data at 0.14.0.
