Small modification due to the supercomputing paper revisions.

NOTE: The pure MPI version (one rank per core) is almost always faster !

!!! Not instantly retro-compatible with any earlier IQS versions, but is a drop-in replacement (iqs:: -> quids::) !!!
Why ? Simulator get passed a previous state and the next state to populate, but not a "buffer state" to swap in anymore.

!! Huge fix to probabilistic sleections !! Otherwise mostly cosmetic.

Huge memory managment and stability update !

Migrated the name IQS to QuIDS to avoid confusion with Intel Quantum Simulator.

Small update that corrected some small errors to average values.

Big optimizations to MPI:

• hugely increased stability (never runs out of memory)
• better load balancing

Small optimizations compared to 2.3.5.

!!! Only retro-compatible with IQS 2.3.0 and later. !!!

New release, with some big optimizations,

!!! Only retro-compatible with IQS 2.3.0 and later. !!!

New release, with some MPI optimizations, and removed NUMA support (which should rely on MPI, with one rank per NUMA node being often optimal).

!!! NOT RETRO-COMPATIBLE !!!
Some interfaces (rule) are changed. See the README for details.

New fully functional release, with full MPI support.

With a lot more functionality, and some important bug fixes (especially with MPI support, which justified deleting older releases).
