Function to get MD5sums of all files in directory that is an emitted element from a channel

Example:

        then {
            def stablefiles = []
            file(process.out.db.get(0).get(1)).eachFileRecurse{ file -> if (!["database-build.log", "database.report.tsv", "timestamp", "taxonomy"].find {file.toString().endsWith(it)}) {stablefiles.add(file)} }
            assertAll(
                { assert process.success },
                { assert snapshot(
                        stablefiles
                    ).match()
                }
            )
        }

Where the process.out.db contains a directory and subdirectories with multiple files, and I want to exclude database-build.log, database.report.tsv, and timestamp because they are variable files

The issue provides no implementation file or test entry point. Start from the shown nf-test then block and the process.out.db channel value, and inspect how nf-test utility functions handle emitted directories and snapshots. Done means a utility can calculate MD5sums for the directory contents while excluding database-build.log, database.report.tsv, timestamp, and taxonomy.
