One-way tubes are more expensive than sorting tubes

[The4codeblocks]

sorting tubes can be configured to act as one-way tubes, so it makes no sense for one-way tubes to be more expensive, even if by half a mese shard

possible actions (contiguous are mutually exclusive):

• replace mese crystal with mese shard
• remove mese crystal entirely
  ----------------------------------
• increase output to 6
  ----------------------------------
• add recipe where a stick is added to a normal tube to make it one-way

[OgelGames]

increase output to 6

This would be the least disruptive change, as it doesn't change the recipe. It also makes sense because 6 plastic sheets make 6 regular tubes.
