New Features

a new option --dvs_emulator_seed is introduced. This option allows the user to use a fixed random seed. The default is 0 which means the emulator uses a system defined random seed.

Bug fixes

Shot noise events polarity was wrongly set to 1 always. This makes the shot noise events are always positive events. Fixed this in emulator.
If not using fixed chipset, v2e was wrongly quitting. This is partially fixed by removing a quitting behavior and resetting both output_width an output_height to None. However, since the AEDAT2 saving requires standard chipset, we recommend user to use HDF5 saving method. For synthetic inputs, please set both output_width and output_width (or using a standard chipset), otherwise there will be errors.
Event Renderer always at 30 fps. Fixed this so that user can preset the frame rate.
The argument skip_video_output still outputs original video and the slow motion video. This is fixed so the behavior matches with the description.
