Internal enhancements and improvements: optimize code and enable parallel processing capabilities

[amyburness]

Optimize code and enable parallel processing capabilities in Trends.Earth. This will decrease processing
times significantly. Ensure that code uses “QGSTasks” where appropriate so that tasks can more easily be parallelized, that users can view percentage completion, cancel tasks, etc. Also use the “numba” library as appropriate to ensure any processing code that
could benefit from just-in-time compilation does so.

Deliverables for Internal enhancements and improvements :

• Optimized processing algorithm for speed

Notes from UR meetings:

• parallel processing using QGIS tasks -> requires a processing overhaul
• user can see the list of jobs but they also need to see the percentage of completion of each job and status category like (processing, success or failure)
• logs may be useful if there is a failure (particularly in the cloud)
