coverage script panics

[Ollrogge]

The coverage.go file will panic when the go-fuzz-headers functions can not translate an input.
E.g. for a byte input:

case "[]uint8", "[]byte":
			randBytes, err := fuzzConsumer.GetBytes()
			if err != nil {
				panic(err)
			}
			fmt.Fprintf(&b, "[]byte(%q)", string(randBytes))

Since LibFuzzer generates random inputs, especially at the beginning, there is no guarantee that all corpus entries will have a valid format. This may result in panics when attempting to transform the corpus into the native format using the libFuzzerSeedToGoSeed function.
