[BUG] A SEGV in `draco::DecoderBuffer::Peek<unsigned int>(unsigned int*)` at `decoder_buffer.h:89:9`

## Description

- Version: Latest commit [4e12ab2](https://github.com/google/draco/commit/4e12ab27d0fe690cf98e96dc33c2bd52e1485163)
- Environment:Ubuntu 20.04.6 LTS, Clang 18.1.8

## Steps to reproduce

```bash
export CC="clang"
export CXX="clang++"
export CFLAGS="-fsanitize=address -g -O0 -fno-omit-frame-pointer"
export CXXFLAGS="-fsanitize=address -g -O0 -fno-omit-frame-pointer -stdlib=libc++"
export LIB_FUZZING_ENGINE="-fsanitize=fuzzer"
export SRC=$PWD
export WORK=$SRC/build
mkdir -p $WORK
git clone https://github.com/google/draco
cd draco && git checkout 4e12ab2
cd $WORK
cmake ../draco
make -j$(nproc)

for fuzzer in $(find $SRC/draco/src/draco/tools/fuzz -name '*.cc'); do
fuzzer_basename=$(basename -s .cc $fuzzer)
$CXX $CXXFLAGS \
-I $SRC/ \
-I $SRC/draco/src \
-I $WORK/ \
$LIB_FUZZING_ENGINE \
$fuzzer \
