Projection::unsetFields() to unset several fields at once

[chanmix51]

It would be nice to be able to unset several fields at once from a Projection:

$this->createProjection()->unsetFields(['field_1', 'field_2', …, 'field_N']);

Any thoughts ?

Good for some kind of dynamic approach. +1

Nevertheless, since unsetField returns $this, I would prefer calling it multiple times.

That's true, the main goal of this method would be to keep the code compact yet readable.

It's good for this issue plz closed :)
