RealSenseRecorder color frames black/too dark

### Checklist

- [X] I have searched for [similar issues](https://github.com/isl-org/Open3D/issues).
- [X] For Python issues, I have tested with the [latest development wheel](http://www.open3d.org/docs/latest/getting_started.html#development-version-pip).
- [X] I have checked the [release documentation](http://www.open3d.org/docs/release/) and the [latest documentation](http://www.open3d.org/docs/latest/) (for `master` branch).

### Describe the issue

First 10-20 frames recorded by RealSenseRecorder.cpp (examples) are completely/too dark when auto-exposure is enabled. This can be fixed by enabling recording immediately at start and then pausing the recording right after, something like
```
rs_config->enable_record_to_file(filename_);
pipe_->start(*rs_config_);
pipe_->get_active_profile()
.get_device()
.as()
.pause();
```
This probably overwrites any existing file even if nothing is recorded.

I tested this (and the fix) on Windows and RealSense L515.

### Steps to reproduce the bug

```python
Enable auto-exposure on RealSense camera and then run RealSenseRecorder.
```
