feat: TrackSelector supports eta-dependent cuts

[paulgessinger]

This changes TrackSelector so that eta dependent cuts can be supplied. To this end, a new nested struct CutConfig is introduced. The existing Config struct is auto-convertible from that struct, and will produce a single cut set for all eta.

You can also supply Config with a vector of absolute eta bin edges and correspondingly sized (N-1) vector of CutConfig structs. The selector will then look up the associated cut value.

Note: the CutConfig properties etaMin, etaMax, absEtaMin and absEtaMax are only supported if there is a single cut configuration with an abs eta bin from 0.0 to +infinity.

The TrackSelector constructor checks consistency of the configuration.

We initially discussed using the Range1D class, but this is not necessary here it seems.
