Minor editing changes for JOSS paper

[mstimberg]

Some minor changes to the bibliography and the formatting of the paper to finalize openjournals/joss-reviews#6590.

This also changes the word "synchronous" to "asynchronous" in the sentence "This allows for asynchronous data reads without the need for a prior download of the entire file." – I hope I did not misunderstand!

Thanks @mstimberg. Actually "synchronous" was correct, although confusing. I think it's better to use the word "partial" instead.

The reading of the remote hdf5 file is actually synchronous, which is not ideal but is necessary for wasm hdf5 in a web worker with emscripten. But it doesn't make sense to point that out in that sentence, so let's use "partial data reads".

EDIT: To clarify even further... the reading is asynchronous w.r.t. the main thread, so it doesn't freeze the UI. But w.r.t. the worker thread, it is synchronous. Again, best to not use that word.

Understood, thanks for the clarification.
