Understand HexType docs :(

Hi @jys0710

I run command:

```bash
$ git clone git@github.com:HexHive/HexType.git
$ ./build.sh
$ export HEXTYPE_LOG_PATH="/tmp/hextype"
```

But, i don;t underestand what happen here:

```bash
. Run HexType

Use the create-clang-typeinfo option or copy the pre-made type info (in the HexType/etc/clang_type_info) into the HexType path as typeinfo.txt file name
Use HexType/scripts/remove_duplicated_line.py in order to remove duplicated lines when you create new type information file
$ $BUILD_DIR/bin/clang++ test.cc -fsanitize=hextype

```
i run :

```bash
$ clang++ -fsanitize=hextype sample.cpp
g++: error: unrecognized argument to -fsanitize= option: ‘hextype’
```

Thanks,
