WIP: AnalysisTop: Adding additional substructure variables for RC jets

ANALYSISTO-1026 - Adding ECF4, tau4, and tau43 to the substructure variables calculated for RC jets. These are under the "UseRCJetAdditionalSubstructure" flag, which is set to false by default. Also included under this flags are variations on ECF[1-4], setting beta to 0. In this way, these variables will only be calculated if this flag is set to true. The variables derived from the ECFs (e.g. C2, C3, etc.) are omitted as the requisite ECFs are present and thus these variables can be calculated further down the line.

In progress: adding the generalised angularities and jet eccentricity as well.
