Update module-info.java

[MachineIntelligence6]

helper package was missing in the file. Fix Error: module org.bytedeco.opencv does not export org.bytedeco.opencv.helper

@HGuillemet Let's append to this all other missing helper modules like that.

I wrote a script to identify source directories without a corresponding export in module-info. It found:

org/bytedeco/cpython/helper
org/bytedeco/opencv/helper
org/bytedeco/qt/helper

and the following directories, which seems to have been introduced after the creation of the module-info:

org/bytedeco/llvm/program
org/bytedeco/tesseract/program

Do you think these 5 directories correspond to packages which must be exported (ie contain Java type that could be accessed by users) ?

[saudet]

Yes, they should be accessible. Thanks!

@AKMANSoft, could you add to your PR these 4 additional exports to their corresponding module-info ?
I don't think I can do it myself without submitting another PR.
Thanks,

[MachineIntelligence6]

Yes no problem. I have added the exports.
