Multiple trial chamber templates have missing or incorrect blocks

The bug

Several trial chamber templates have missing or incorrect blocks.

Chambers

• assembly
  • One of the blocks in left_staircase_2 and right_staircase_2 is tuff bricks instead of chiseled tuff bricks.
• chamber_2 generates without six copper bulbs (top and bottom) on three of its pillars on one corner.
• chamber_4 has one of its pillars missing a tuff bricks block.
• chamber_8 has an incorrectly rotated trapdoor (MC-270614).
• eruption
  • One of the pillars is missing two waxed copper blocks on the top.
  • One of the pillars is missing one waxed copper block on the top.
  • A block of tuff bricks is misplaced near the top of two of its pillars.
  • A block on the copper floor of quadrant_1 is incorrect, with waxed oxidized cut copper instead of waxed oxidized copper.
• slanted has several tuff bricks instead of polished tuff on the roof between pillars near the center.

Corridors

• end_1
  • There is a misplaced waxed copper block instead of tuff bricks.
  • One of the sides is missing middle and lower waxed copper bulbs, making the room asymmetrical.
• end_2
  • There are four apparently misplaced tuff bricks on the roof.
• straight_6 has inconsistent copper blocks on the corner of staircases.

Hallways

• corner_staircase has a waxed copper block instead of a tuff bricks block in one corner.
• left_corner is still missing several blocks.
• right_corner is still missing chiseled tuff bricks, and does not replace certain blocks with air.
• straight_staircase has chiseled tuff bricks instead of tuff bricks behind one of the waxed oxidized cut copper stairs.
• upper_hallway_connector
  • There is a waxed copper block on the top floor instead of waxed oxidized copper.
  • The placement of the top copper bulb is offset one block compared to the bottom one, unlike other templates.

Intersections

• intersection_3 has nine tuff bricks on the roof near the top of its pillars instead of polished tuff.
