crash on exposure slider change

[leoyala]

🐛 Bug Report

When the exposure slider is changed rapidly, the camera does not seem to have time to change the exposure time at the hardware level, causing a runtime error because it cannot access some internal resources that might be unavailable while the exposure time is being changed.

🔬 How To Reproduce

Steps to reproduce the behavior:

1. start the software
2. Connect any XIMEA camera to computer
3. Adjust the exposure time rapidly using the slider

Code sample

Environment

• OS: Linux
• CMake version: 3.22.1
• Compiler: gcc
