Election for Jason Koch as Committer on Eclipse Memory Analyzer

Jason Koch has made a number of very valuable contributions to the Eclipse Memory Analyzer, the most notable ones being changes to speed-up the heap-dump parsing process by extensively using parallelism.
Jason started contributing to MAT in 2019 and kept his interest in the project - making further contribution and actively participating on the MAT developer mailing list.
He has deep understanding of MAT's code base and valuable ideas on possible improvements and the future development of MAT.
