Enable upload for all our supported image formats

Description

We support many other formats other than the ones we currently allow. We also lost jpg (not jpeg) support in PR #51 (https://github.com/roboflow/roboflow-python/pull/51/files#diff-05ecffcd056f67631588da1975ca43403a88910478c8435876abcdd85b7a8025)

Let's fix it, but later we have to change to look for minetypes, not only file extensions.

We use PIL format, it is normalized to JPEG. We have to understand this problem better.

I think the issue is with invalid images, I see a lot of it in other projects.

We need a verbose mode explaining why it failed.

I tested here:

>>> from PIL import Image
>>> image = Image.open("image.jpg")
<PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=4080x3072>
>>> image.format
"JPEG"

The issue is probably with invalid images. We can use filetype lib to get the real type and give a good warning when file extension doesn't match expected mime extension:

>>> import filetype
>>> kind = filetype.guess("original.jpg")
>>> kind.extension
'avif'
>>> kind.mime
'image/avif'

Closing this one because I merged #284 with a more complete solution.
