Add "Prediction Study" filter to the search bar

[cginer]

It would be nice to be able to filter inversions by prediction source. Similarly to the "Validation Study" filter already available.

Only 'Prediction study' or also 'Prediction method' ?

[cacereslab]

Maybe just prediction study? (unless creating both options is relatively simple)

[RuthGG]

There are now available 3 new filters that have been added to the search bar:

• Prediction Study
• Prediction Method
• Prediction Name (e.g. CINV_delly_INV00000339)
