the Manifests codepath was calling setupReportFormat on a mutable global map, which means that calling Manifests from different gothreads is an error, and can produce a panic with this (abbreviated) traceback: fatal error: concurrent map writes goroutine 668 [running]: runtime.throw(0x27cb973, 0x15) /usr/local/go/src/runtime/panic.go:1116 +0x72 fp=0xc003a8c710 sp=0xc003a8c6e0 pc=0x437892 runtime.mapassign_faststr(0x23fc3a0, 0xc019650120, 0x27a837d, 0x6, 0xc00012f408) /usr/local/go/src/runtime/map_faststr.go:211 +0x3f1 fp=0xc003a8c778 sp=0xc003a8c710 pc=0x414811 github.com/databus23/helm-diff/v3/diff.setupDiffReport(...) /go/pkg/mod/github.com/databus23/helm-diff/[email protected]/diff/report.go:99 github.com/databus23/helm-diff/v3/diff.(*Report).setupReportFormat(0x3dafe80, 0x27a5ada, 0x4) /go/pkg/mod/github.com/databus23/helm-diff/[email protected]/diff/report.go:67 +0x111 fp=0xc003a8c7b0 sp=0xc003a8c778 pc=0x20e7291 github.com/databus23/helm-diff/v3/diff.Manifests(0xc009ffaf60, 0xc009ffb3e0, 0xc0061f73e0, 0x1, 0x1, 0xc0061f7300, 0x5, 0x27a5ada, 0x4, 0x2b26460, ...)
