Fix optifine blurring GT creative tab icons by scaling logos to 32x

[MCTian-mi]

What

OptFine will try to scale up item/block icons whose size is not a multiple of 16, in this case, GT logos are 17x, and got scaled up to 80x, which caused it to look really blurred.

This PR fixes this in a brute-force approach: scale these two icons 16 times larger (17 pix -> 272 pix)

When I added the logo item I contemplated whether to make the texture 17x or 32x, I chose 17x at the end because I didn't think there were any consequences apart from forge printing two warning statements. Oh well.

Using 32x texture and setting XY scale of the logo model json to 2 might be a better approach. Probably needs to fiddle a bit around offsets. (Spawning the logo item in your inventory makes it easier to see the offset fyi)
