Feature request: include hdf5 library version as attribute in H5 file and run_info JSON

[warrenmcg]

Hi @pimentel and @pmelsted,

The sleuth issues forum has received two separate reports from users that relate to an unexpected incompatibility between the hdf5 library version used in kallisto and that used in the rhdf5 library that underlies the read_kallisto_h5 and write_kallisto_h5 functions (pachterlab/sleuth#120 and pachterlab/sleuth#175).

Thus, I want to propose a feature request.

The incompatibility could be more easily identified in sleuth if kallisto included in the kallisto HDF5 output file an additional attribute to include the hdf5 library version used to construct the file, so that it could be easily accessed and checked against the hdf5 library version used by rhdf5 when reading the file. I think that would be the easiest solution from sleuth's end, though it could also work to use the run_info.json file. I think including the library version in both locations would be helpful to users.

I can't code in C++; otherwise, I would make the change myself.
