Mqt.ddsim

This release improves the workflow for building wheels and drops support for python3.6.

What's Changed
- Pruned directories from external submodules in MANIFEST.in to reduce size of sdist to below one megabyte.
- Use ninja as generator target on supported plattforms in setup.py to improve wheel build times
- Stop building wheels for python3.6 as it's eol since a couple months

**Full Changelog**: https://github.com/cda-tum/ddsim/compare/v1.11.2...v1.11.3

This release is for fixing a bug that caused problems finding DLLs under Windows and for a more elaborate documation.

What's Changed
* Fixed bug on finding DLLs on Windows due to relative imports
* Extended documentation to include examples for installation on different OS with pip (to be extended further)

This release adds the path simulation framework proposed in

L. Burgholzer, A.Ploier, and R. Wille, "[Exploiting Arbitrary Paths for the Simulation of Quantum Circuits with Decision Diagrams](https://iic.jku.at/files/eda/2022_date_exploiting_arbitrary_paths_simulation_quantum_circuits_decision_diagrams.pdf)," in Design, Automation and Test in Europe (DATE), 2022.

To this end, two new Qiskit backends are introduced: the `path_sim_qasm_simulator` and the `path_sim_statevector_simulator`.
For further details, see the README and the corresponding paper.

Highlights:
* Got rid of boost program-options dependency in favor of cxxopts
* Create dependabot.yml for submodules, github-actions, and pip
* Made `shots` option optional in qiskit backends (default value 1024)

Smaller changers:

* Versionbump to v1.10.0
* Added files to .gitignore
* Updated README to remove mentions of boost
* Updated CIBUILDWHEEL version
* Added Pyproject.toml
* Tests for cpython3.10 since qiskit-terra supports this now

- Pull in fix for iic-jku/dd_package25
- Additional wheels for Python 3.10 and musllinux
- Source install of via pip or setup.py uses available cores and native optimizations
