v1.0.3

What's Changed

• Check return values when connecting to/creating a database by @matejmatuska in #2
• Fix memory handling. In the case of a non-valid input file, the program warned about the situation,
  but in the destructor was accessed uninitialized memory. This leads to a Core dump.

New Contributors

• @matejmatuska made their first contribution in #2
