monte_carlo_tag on momentum with cuts

[jacanchaplais]

Currently, clusters formed which get passed to graphicle.select.monte_carlo_tag() must be masks over the full four-momentum, without cuts to $p_T$ or $|\eta|$. This is enables a consistent view for the ParticleSet.final mask. Attempting to apply cuts to the momentum before clustering yields in a shape mismatch. Explore ways of resolving this.

Potential solutions:

• add a parameter cuts, a mask representing the cuts made to the momentum
• pass the momentum of the clustered particles, so direct correspondence to elements in full record becomes unnecessary
