Error when using pypcd with Python 3.8 about pypcd HOT 3 OPEN

Hi there!

Can you import the following requirements without error?

import numpy.lib.recfunctions as recfuncs
from sensor_msgs.msg import PointField
from sensor_msgs.msg import PointCloud2

from pypcd.

@DanielPollithy Hi I'm also facing the same problem and can also import above dependencies.

However, my traceback is different than above issue.!!
