panicparse no longer works with backtraces from go1.22 and go1.23

[ncw]

I wrote a simple program and killed it with SIGQUIT with various go versions and captured the backtraces

package main

import "time"

func main() {
	time.Sleep(time.Minute)
}

With go1.21.4 panic parse works fine backtrace.go1.21.4.log

However with go1.22.5 backtrace.go1.22.5.log and go 1.23.2 backtrace.go.1.23.2.log panicparse does not recognise the backtrace and does nothing.

I think this change in the backtrace is probably the breaking one but I haven't looked in the source yet!

Thanks, indeed. I'll gladly accept PRs or I'll work on this relatively soon.
