/**
* Extracts the array of _compound certificates_ given two arrays of _base certificates_.
*
* Since **db-sync** projects _compound certificates_ as the result of the _split_ of relevant certificate properties
* in the tables dedicated to _base certificates_, in order to reduce the number and the complexity of SQL queries
* performed by `queryCertificatesByIds`, we perform only simple direct queries in the tables dedicated to _base
* certificates_.
*
* Example: given an array of `reg_cert` and an array of `vote_deleg_cert`, the result is an array of:
* - all input `reg_cert` which can be neither `vote_reg_deleg_cert` nor `stake_vote_reg_deleg_cert`,
* - all input `vote_deleg_cert` which can be neither `vote_reg_deleg_cert` nor `stake_vote_reg_deleg_cert`,
* - the array of `vote_reg_deleg_cert` (it includes also the partials `stake_vote_reg_deleg_cert`)
*
* @param certs1 the first certificates array
* @param certs2 the second certificates array
* @returns the array of: first certificates array, second certificates array, compound certificates array
