[Bug]: Support special versions of pytorch in setup.py

1

### What happened? Special versions of pytorch adds a plus sign and some text to the version number like `1.12.1+cpu` or `1.12.1+cu116`. When installing Heat, these packages get replaced (`1.12.1`)....

[Bug]: factories.array illegal parameter combinations copy & split

1

### What happened? ht.array creates a new DNDarray on the CPU when the arguments copy = False and split >= 0 are passed. This should not happen. In addition, copy...

**Description** A clear and concise description of the bug and the associated functionality. various bugs when using index arrays for indexing on distributed one-dimensional DNDarrays. **To Reproduce** Steps to reproduce...

Upgrade legacy code

1

**Description** After raising the minimum dependencies in #1573, legacy code targeting older versions of PyTorch exists. In addition Python 3.9 allows built-in collection types for annotations. **Additional context** [Short summary...
