EBI experiment data for full run

Currently, we ask the use to add the platform and instrument_model to the user via the prep template. Additionally we hardcode library_source, library_selection, and library_layout. However, all these fields should be dropdown menus per prep template.

The full list of valid options for those are: https://www.ebi.ac.uk/ena/submit/preparing-xmls

Note that this hasn't been closed and would need some large changes.

Anyway, some valid values from EBI:
