pycolmap.Image constructor fails in 0.2.0

Hi,

I observed an error that occurs for me when constructing an Image object manually:

import pycolmap

points = [pycolmap.Point2D((100, 200))]
pts = pycolmap.ListPoint2D(points)
image = pycolmap.Image("image.png", pts)

In 0.1.0 this used to work fine, while in 0.2.0 it raises the following error:

Traceback (most recent call last):
  File "image_construct.py", line 5, in <module>
    image = pycolmap.Image("image.png", pts)
RecursionError: maximum recursion depth exceeded while calling a Python object

Note that when default-constructing the object without point list it also works fine.

Environment: Python 3.8 on Ubuntu 20.04, pycolmap 0.2.0 installed from PyPi

Hi, the problem is that pybind fails to resolve the constructor here. You can either serve the points via the keyword argument:

image = pycolmap.Image("image.png", points2D=pts)

or use the much simpler auto conversion:

import pycolmap
image = pycolmap.Image("image.png", keypoints=[(100,200)])
# or
image = pycolmap.Image("image.png", [(100,200)])

On branch fix-image-constructor I pushed a fix which should also resolve your issue.
