[WIP] Refactor JPEG 2000 processing for performance improvements

[Copilot]

Cloud agent has begun work on Read the attached PD... and will update this pull request as work progresses.

Original prompt

Read the attached PDF to understand the memory efficient push/pull pipeline for JPEG 2000 compression/decompression. The idea is to exploit the fact that the multi-component transform, spatial wavelet transform and block coding processes can all be performed incrementally. Please read carefully section 3, 4, and 5. With the clear understanding of this paper, please plan for refactoring the current code to improve the end-to-end processing speed including both encodding and decoding. The speed should be firstly measured in single threaded environment, then should be measured in multi-threaded environment. Please use SIMD technologies for both intel SSE/SSE2/SSE3/SSE4/AVX2/AVX512 and ARM NEON as much as possible to make the cod faster!
