Description

The supported return modes for some Hesai sensors were not correct:

• AT128 does not support all return modes Nebula allowed
• XT32 supports more return modes than Nebula allowed

Return mode Dual is a relic from Velodyne's driver and is kept in Nebula for backwards-compatibility reasons. However, the internal representation has been updated to the more precise, sensor-specific return modes (LastStrongest or LastFirst depending on the sensor).

Review Procedure

Use nebula_evaluation to test return modes on these sensors.
