Fix fields types for sc3_array_t

Proposed changes:

This PR fixes the ,,sc3_array_t::ecount and ,,sc3_array_t::ealloc types from ,,int to ,,size_t as it is in sc_array_t. It will be beneficial for solving some type conflicts in shared memory partition and iteration algorithms.

Wondering, why do we have 76 changed files? Is there no way to have the origin and new branch receive the same merges beforehand?

I tried to push my feature-sc3 with merged the latest develop branch into yours feature-sc3. It caused the significant diff. Now I undid the latest develop merge.

I suppose, it caused the CI fail with MacOS, as I think this issue was solved on the develop branch.

The one suggestion would be to update ours both feature-sc3 branches with the newest develop.

Thanks! Yes, updating both branches will make sense. I'll do this once I've released the next version of sc.

Using size_t consistently for memory sizes/locations makes sense. I would just suggest to rename a standard int variable like 'i' to 'iz' or similar to avoid any risk of confusion. ecount etc. can remain as is.
