This function add de distance and duration of the Shortest Path Between Two Points. Its use the osrmRoute function of osrm library, that build and send an OSRM API query to get the travel geometry between two points. This function interfaces the route OSRM service. The principal contribution to this function it´s yo consider the CRS of the input coordinates, and only output the distance and time variables of the procedure.

1 | ```
byosrmRoute(src_dst, crs)
``` |

`src_dst` |
Dataframe with four variables: x of source, y of source, x of destination, y of destination. x and y are plain coordinates in the defined CRS |

`crs` |
Coordinate Reference Systems (CRS) |

Return a DataFrame with:

`src_dst` |
The input DataFrame with 2 new variables "distance" in meters and "duration" in minutes |
