Updated code to keep it running on Ubuntu 22.04 / python 3.10.12 / March 2024

[AmmarkoV]

The code has been updated with the following changes :

1. requirements now lists all requirements (including cython, scikit and others that where not there previously )
2. compatibility with numpy 1.21> np.float is fixed using the method suggested by numpy
3. imresize is no longer available using
   from scipy.misc import imresize
   and is replaced with
   from skimage.transform import resize as imresize
4. python calls have been replaced with python3 since python is no longer available if the python-is-python3 package is not installed

It is the first time using coco-analyze so unfortunately I have no data to compare against the previous version :
however :
make all
python3 run_analysis.py ./annotations/person_keypoints_val2014.json ./detections/fakekeypoints100_keypoints_val2014_results.json ./results/fakekeypoints100 fakekeypoints100 1.0
seems to be working fine
