Better failure messages for disposals test

[PowerfulBacon]

Perhaps the messages for the disposals test are a bit unclear, we should concatenate failures so they look something like:

Report:
1: Chemistry: 14/57 disposal bins failed to reach chemistry. (<70%)
2. Disposal bin at (1,7,4) failed to reach 17/18 locations.
3: Engineering: 53/57 disposal bins failed to reach chemistry. (>70%)

Failures:
1: (1, 2, 3), (1, 2, 3), ...
2: ...

If some percentage of bins fail to reach a location, then it should be reported as bins failing to reach that location, otherwise it should be treated as that bin failing to reach locations.

Common faults:

• No inputs (<20%) ever reach the desired destination and reach disposals/cargo instead: A filter doesn't exist on the network.
• Most (>50%) inputs reach an incorrect location that isn't disposals/cargo: A filter likely exists on the network but leads to an incorrect location, or the area should be considered valid and the valid location list needs to be updated.
• Lots (>40%) of disposal units incorrectly end up in disposals/cargo, but some (>20%) are arriving at the destination: Make sure an unsorted filter has been added as the final node in the loop before the output in disposals which leads back into the network to allow for inputs near the end of the disposals loop to pass through the entire loop.
• A disposal unit fails to reach most (>60%) of the destinations: The disposal unit is connected to filters, but is failing to enter the disposals loop correctly.
