fix UTF8 string encoding

[ilia-kats]

h5createAttribute/h5writeAttribute needed the argument to be "UTF-8" and passed it to H5Tset_cset, which needed the argument to be "UTF8". Therefore, setting the encoding to UTF-8 failed. This patch changes h5createAttribute and h5writeAttribute to accept "UTF8".

Thanks a lot for pointing this out. I'm inclined to go the other way and use the "UTF-8" notation, principle because that's the official name of the encoding.

I see there's also some inconsistencies where this is set either via the cset or encoding arguments depending on whether its and attribute or a dataset that's being created. I'll think I'll set both to use encoding going forward, but I'll only deprecated the cset argument so it'll still work if you're currently using it.

Thanks for the feedback, I updated the PR to use UTF-8instead of UTF8.

Did you see that I made a pull request on your own repo with some additional changes? Those pass R CMD check (
https://github.com/grimbough/rhdf5/actions/runs/1515325296)

It'd be good if you could look over those, so we can keep in sync. I can't keep track of what you're doing with these force pushes.

[ilia-kats]

Apologies, I didn't get an email for your PR and so I missed it. I merged it now, thanks.

[grimbough]

No problem. I'll wait until the CI check have passed, and then merge this master and push to Bioconductor.

That is, assuming the changes do what you want!

[ilia-kats]

Great, thanks. My usecase for the moment is pretty much covered by the h5createAttribute/h5writeAttribute part, so yeah, it does what I want :)
