Fix bug when reading scalar datasets

[ehennestad]

Fix issue #120

Add a check in ZarrPy/readZarrfor whether starts, ends or strides are integers, and wrap them in a list if true.

Some alternatives:

• wrap in array to ensure type is same as what is received from MATLAB when these are non-scalar?
• simplify check and assume all is scalar if one is scalar

Thank you for contributing!!! Looks reasonable to me.

Looks like we don't have workflow enabling tests to run for PRs from forks, let me fix that.

I was going to ask to add a test, but it seems currently there is no way to write a scalar dataset (with shape that is a scalar value) using this project (Is that a significant limitation?). For now, if you are ok adding starting_time or a different sample scalar dataset to test/dataFiles and adding a simple test in test/tZarrRead.m to read it, that would be great! If not, you can add a task for us to add a test later.

Even if you are not able to add a test, could you please do a dummy commit to trigger the tests workflow on the PR? Thanks!

I can add a test. Being able to write scalar datasets is out of scope at the moment, we will first work against full support for read

Sounds good, thanks!

Yes, sorry, didn't meant to imply you have to work on writing scalar datasets, just thinking if that's something we should look into in the future.

Looks good to me!

As mentioned - would be nice to have a test though, and to make sure existing tests run fine.

Thanks for contributing!
