Ambiguity regarding AVIA/MID360 config and preprocessing

[JoLichtenfeld]

Hi, thanks you so much for this very useful implementation.

I use it mostly for our Livox MID360 lidars. However, I am somewhat confused about the names of the config file.
In mid360.yaml, the lidar type is set to "1 for Livox serials LiDAR" which translates to LID_TYPE=AVIA here. Maybe it would make more sense to rename this to LIVOX since it applies to all Livox serial LiDARs?
Then also here I see that the enum LID_TYPE has an element MID360. This in return refers to the mid360_handler in preprocessing.cpp which takes a PointCloud2 as input and assumes that no timestamps are given.

So what is the recommended way to use FAST-LIO with a MID360? To select lidar_type=1? In which case would one use lidar_type=4?

Thank you!
