use prepared abcd in matching

[jacobvjk]

closes #14

• run_matching() and run_match_prioritize() now both use the abcd_final.csv as input for the abcd, instead of the raw abcd file
• this means that abcd_final now simply has to be prepared once using prepare_abcd() as the very first step of the analysis and all following functions expect that same data set
• this is a prerequisite for implementing the information architecture as agreed upon in https://dev.azure.com/RMI-PACTA/2DegreesInvesting/_workitems/edit/11852
