Double-Free of ImageReadJPEG

[NigelX]

Hi

I found an crash erro.

System info：
Ubuntu 20.04 : clang 10.0.0 , gcc 9.3.0

DIPliB Release v3.0.0

commit:7db848500f4cc5db676b32e9a95dcbc94d976339

[poc1.zip](https://github.com/DIPlib/diplib/files/6966666/poc1.zip) (edit: careful with this, looks malicious)

---

Verification steps：
1.Get the source code of DIPliB
2.Compile the DIPliB and poc.cc

$ cd diplib
$ mkdir build && cd build
$ cmake ../ -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_FLAGS="-O2 -fno-omit-frame-pointer -g -fsanitize=address" -DCMAKE_CXX_FLAGS="-O2 -fno-omit-frame-pointer -g -fsanitize=address"
$ make -j 32
$ sudo make install
$ cp src/libDIP.so ./
$ clang++ -g poc.cc -O2 -fno-omit-frame-pointer -fsanitize=address  -fsanitize-coverage=bb -I/usr/local/include -lDIP -L. -Wl,-rpath,. -o poc

3.run poc

$ ./poc crash.jpg
