Add organoid icon and color on Patient View

[inodb]

Add an organoid icon and color for samples of SAMPLE_CLASS === "Organoid" on the patient view:

Minor refactoring:

• Import Icons as SVG, so one can directly edit the SVG in e.g. Illustrator (rather than having to mess around with functions). Not sure if it's ok to disable typing of SVGs? Seems like we do that in e.g. the OncoKB package, but not in the main package. Can use requires() as alternative
