error: static assertion failed due to requirement 'always_false<unsigned char *>': => Type not supported yet

Hi all,
I'm trying to port the example `woff2` fuzzer to `bazel`. I have prepared the project so I can run simple tests but when I try to mimic the original `LibFuzzer` entry point I get an error.

This is the code

```
#include
#include
#include "fuzztest/fuzztest.h"
#include "gtest/gtest.h"

#include

void ConvertWOFF2ToTTF(uint8_t* data, int size) {
}
FUZZ_TEST(AlbertoFuzzTest, ConvertWOFF2ToTTF);

// Entry point for LibFuzzer.
extern "C" int LLVMFuzzerTestOneInput(const uint8_t* data, size_t size) {
std::string buf;
woff2::WOFF2StringOut out(&buf);
out.SetMaxSize(30 * 1024 * 1024);
woff2::ConvertWOFF2ToTTF(data, size, &out);
return 0;
}
```

This is the output when I run `bazel run --config=fuzztest --copt=-I./include :alberto -- --fuzz=AlbertoFuzzTest.ConvertWOFF2ToTTF`

```

Which type should I use instead? Any other way to fix it?
