Unused pixels in brewing stand base texture

Relates to: MC-176095 MC-199660 MC-208679 MC-250985

The bug

In both the vanilla textures and Programmer Art, many regions of the brewing stand texture go completely unused. The texture mapping between the default textures and Programmer Art differ as the brewing stand is currently one of only two blocks where the model differs between the two packs, however the same amount of pixels currently go unused.

How to fix

An easy fix - just replace the vanilla brewing stand base texture file with the one attached, and replace Programmer Art's with the fixed Programmer Art brewing stand base texture as well.

I've attached a third texture to this ticket, which is intended for use with MC-262464, as that ticket depends on the repurposing of unused texture regions. If MC-262464 is fixed, then that texture should be used to replace the vanilla texture instead.
