Improve prediction

The goal is to be able to display the atom numbers and correct highlight for predicted NMR spectra.

To test used the molecule from the snapshots (ethyl vinyl ether).

The atom numbers could be displayed by default.

1. In the prediction panel, add the toggle to display atom numbers, on by default

2. Assignment not highlighted ?

The atom 5,6 does not have the yellow highlight on the top (could be the result of a change we did about the position of the assignment and I would have to change the webservice)

3. Display the atom numbers as assignment in the table
