Fix encapsulated pixeldata handling

[weanti]

Fix constructing frame offsets for encapsulated pixel data.
Fix reading frames from encapsulated pixel data.

Remove restrictions for bits stored value, because it is not valid in all cases e.g. CT.

Hi @weanti,

This looks great! Thank you for doing this work.

Could you explain what kinds of DICOM you are working with? Do you have some sample DICOMs I could use for testing?

You probably saw the other PR (#102): we should probably merge that first, since it covers some of the same ground.

Hi,

thank you for your response.
In the meantime I did further testing and I found problems. Memory overwrites and offset handling problems.
Sure, I try to attach or send some test files. Btw I used JPEG2000 encoded DICOM images.
First I need to polish this PR.

OK, let's tag this as a draft for now.

I think I solved the problems.
I have attached a bunch of DICOM files. See the readme.txt for important properties.
UPDATE: uoloading files doesn't seem to work. Here is a link for a shared zip file: https://drive.google.com/file/d/1UPgq89YLx94XyiuGOupR2t0LtgQ4VnkS/view?usp=sharing

@jcupitt What's your opinion about this PR? The other PR (the one before this) is updated. If that is merged, then I'll rebase and update my PR.

Hi @weanti, sorry, I was on holiday and then got distracted by other projects.

I'll look this over again now.

... I saw one final tiny issue in #102, when that's resolved I'll look at this more closely.
