Flask v2.2.0 changes some keyword argument

[jnguiot]

Initial conditions:

• Flask-Images==3.0.2
• Flask==2.2.2

Reproduction step

Use the imgresizer on a valid image. EG:

http://localhost:5000/imgsizer/test.jpg?h=480&m=crop&v=Yy8dVw&w=640&s=xxxxxx

Observed Behavior

The URL returns a 500 error.
Exception is:

2022-09-24 17:19:29,310 ERROR werkzeug Thread-310 : Error on request:

    return send_file(cache_path, mimetype=mimetype, cache_timeout=cache_timeout)
TypeError: send_file() got an unexpected keyword argument 'cache_timeout' datefmt=

Expected behavior:

Image should be downloadable without a 500 error.

First analysis

Flask has updated their send_file function by deprecating some key word argument. See https://github.com/pallets/flask/blob/73b9bacbf7e7440e5a8a65e61fecfe3d0ce75579/CHANGES.rst#version-220 . Code update from flask_image is required.
