Crafter UI sprites do not support translucent pixels

More loosely relates to these issues: MC-144009 MC-145821 MC-164001 MC-165403

The bug

If translucent pixels are present in any of the three sprites the crafter uses for its inventory, they are rendered completely opaque in-game, which is not correct.

How to reproduce

1. Download and apply the attached resource pack

2. Enter a crafter

3. Observe

Expected results

Translucent textures where the arrow is as well as for disabled slots.

Actual results

Entirely opaque.
