feat: image chunking

[eherozhao]

What was the problem/requirement? (What/Why)

Before we have native OpenJD feature Chunking (see RFC for more details https://github.com/OpenJobDescription/openjd-specifications/pull/54/files), we would like to have this feature in After Effects submitter for customers to have their image sequences chucked to increase the total rendering time.

What was the solution? (How)

1. The submitter allows customers to pass in a param Frames per task (ChunkSize) and then depending on this number and the range of frames, there will be chunked tasks and assigned to workers.
2. Rewrote PS script to Python to be more portable.

What is the impact of this change?

1. Customer can use chunking in AE submitter.

How was this change tested?

Submitted AE job with video output and image output.

The image job will be split to multiple tasks based on chunk size. Example as follows.

I tested the following sceanrios:

1. 0-2999 frames for video output.
2. 0-2999 frames with 1000 chunk size => 3 chunks or 3 tasks
3. 0-2999 frames with 1 chunk size => 3000 chunks or 3000 tasks
4. 100-299 frames with 300 chunk size => 1 chunk or 1 task
5. 100-299 frames with 299 chunk size => 2 chunks or 2 tasks, the second task only has 1 frame.

Was this change documented?

Is this a breaking change?
