Rename Species as another proper name in organ-anatomogram

[ke4]

The species property in the Anatomogram.js currently passed to this other components:

• https://github.com/ebi-gene-expression-group/organ-anatomogram/blob/master/src/json/svgsMetadata.json
  species sometimes use in this file as organ and sometimes as species. We should fine a better word for this.
  When we have a decision, then apply it in these files:
  • json/svgsMetadata.json
  • Anatomogram.js
  • AnatomogramSvg.js
  • Assets.js
  • Main.js
  • Switcher.js

If we fixed this, then we should rename all along the other props and method names that goes along with this.

• https://github.com/ebi-gene-expression-group/atlas-components/blob/5e49a70e0ad77477d993ba79237d80ea43437943/packages/atlas-anatomogram-experiment-table/src/anatomogramExperimentTable.js#L92. -> In this bit of code it looks like that should be called organ and not species. This code should be refactored anyway, as this long conditinal statement could be replaced a much cleaner and simpler JSON file. I already created a ticket for that: Make code cleaner in anatomogramExperimentTable.js atlas-components#180
  Although we might not even use this component. If we don't use it, then we should deprecate it.

Suggestion from Christina to call this field to organism_part.
There is another suggestion from @lingyun1010 to call it top_view.

We did not have enough time on the sprint planning meeting to have a final decision.
I am going to organise a separate meeting where we could properly find a solution as there might be other issues and not just a wrongly named property.

We had a meeting related to this ticket with @sfexova @lingyun1010 and Christina.
We made the following decision:

• @lingyun1010 revise all the documentations / SOPs regarding anatomograms till the end of this year
• as this is not a high priority ticket, we won't touch the code for now and probably do it when we add more anatomograms

I am going to leave this ticket as open, but put back to our backlog.
