Getting "JSONDecodeError: Expecting value" error #10

Hello!

I just updated my installation of thermal_base since it now support M2EA (thanks!!!), but I now get an error while reading a file (either one H20T file that worked well previously, or a Mavic 2EA file:

Code:

from thermal_base import ThermalImage
image = ThermalImage(image_path="./DJI_20220113111141_0001_T.JPG", camera_manufacturer="dji")

Error:

JSONDecodeError: Expecting value

Alright, I think I just didn't have exiftool in my path when I started Anaconda and adding it afterwards without restarting didn't translate...

Fixed.
