[issue] How can I modify the raw sensor data generated from SVL?

[mgcho0608]

I need helps to solve these questions. Honestly, these questions are not about install and constructing SVL server, but I hope that I can get any help due to official close down of LGSVL github.

1. I think there should exist any function or code that generate sensor frame data which is received by apollo. Then, it would be possible for me to modify that code to change or perturb sensor raw data before apollo. But, I couldn't find such codes or functions. If such codes are exist, where is it and how can I modify them?
   Ex: https://github.com/lgsvl/LidarSensor/blob/master/LidarSensor.cs, https://github.com/lgsvl/RadarSensor/blob/master/RadarSensor.cs

2. When I construct external SVL server and use client in my local, the simulation basically receives sensor raw data from the server asset, maybe. But within the same context of question1, I heard if I locate sensor assets in my local client's directory, the simulation loads sensor raw data from it, not from the server. But I couldn't find the reason for it, and even not sure that it is true.
