Exception becuase of missing math package

[hcarter333]

Getting the following from pytest:

Traceback (most recent call last):
  File "/home/hcarter333/datasette-haversine-point-path/datasette_haversine_point_path/__init__.py", line 36, in haversine_point_path_sql
    tx_x = cartesian_x(lat1,lon1)
  File "/home/hcarter333/datasette-haversine-point-path/datasette_haversine_point_path/__init__.py", line 7, in cartesian_x
    return (math.cos(f*deg2rad)*math.cos(l*deg2rad))
NameError: name 'math' is not defined

I'll add the path and I'll also add the dependeny to pyproject.toml.

math package now found. The new issue is that my 'constant' deg2rad is missing.

That fixed this issue.
