Dolt database import of this data

[jycor]

Hi, I work for DoltHub, the maintainers of Dolt, a version controlled database (think Git and MySQL had a baby). This is shameless self-promotion, but we took the liberty of importing the data into Dolt and posting it on DoltHub.

By importing to Dolt, I was able to address the following issues:

1. https://github.com/microsoft/RoadDetections/issues/6
2. https://github.com/microsoft/RoadDetections/issues/11

The data is also easier to query, update, and modify.

My dream would be for you all to move this project to DoltHub, but short of that maybe put a link in your README to the Dolt version?
