segfault with gcc > 7

[sassy-crick]

Describe the bug
The program is segfaulting with more recent compilers, in particular with gcc 11.x.y

Additional context
igor -run_demo
results in a segfault
Steps to reproduce the bug
As above
Expected behavior
To fun the test program correctly

System information:

• IGoR version: 1.4.0 / 1.4.2
• OS: Debian Buster
• Compiler and compiler version: gcc-11.2.0 and gcc-11.3.0

Compiling the code with newer, i.e. more recent compilers like gcc-11.2 or gcc-11.3 lead to a segfault in the demo program.
The attached patch fixes this in Aligner.cpp, so the demo program can be used. This also fixes another problem in Utils.h.
In Utils.h #include <string> is missing but I am sure you can patch that yourself.
There are still some small buffer overflows, which you can see for yourself if you compile with the -g3 -fsanitize=address flags. See here for more information:

I had some issues with compiling but was able to successfully compile and run the demo (without seg fault) using intel 2020 c compiler.

./configure CC=icc CXX=icpc --prefix=path/to/directory

Hope this helps someone! :)
