bug

The keyword arguments aren't passed through on .matrix.

code example

matrix_locations=1 didn't make it to the backend.

from routingpy import Valhalla
from pprint import pprint

coords = [[13.413706, 52.490202], [13.421838, 52.514105], [13.453649, 52.507987], [13.401947, 52.543373]]
client = Valhalla(base_url='http://localhost:8002/')
matrix = client.matrix(locations=coords, profile='pedestrian', dry_run=True, matrix_locations=1)
print(matrix)
