Reduce the node_modules package size from ~2GB

node_modules size is too big.
The size of the opencv4nodejs is 424MB
The size of the opencv-build is 1.49GB
How can i reduce this enormous size to a more reasonable one?

Start by examining how the node_modules package includes opencv4nodejs and opencv-build, whose sizes are reported as 424MB and 1.49GB. Determine which build or packaging configuration controls those contents and define a reasonable target size; the issue does not identify specific files or tests.
