change library and Python package names to GaudiPartProp

Graeme Andrew Stewart authored 1 year ago and Marco Clemencic committed 1 year ago

This is a port of the LHCb PartProp service into Gaudi.

Namespace for the service is updated to be part of Gaudi.
Various examples and tests are all ported.
Copyright and license are updatded to match Gaudi.
Test algorithm is converted to a plain Algorithm
and not a GaudiAlgorithm.
Considerable clean-up of Python parts to improve flake8
and pylint compliance. (There are some import statements
that have side effects, which are excepted from tests,
F401.)

Add support for slice-based access to `GaudiHandleArray` so that the
following works:
```
   for h in myHandleArray[1:]:
     ...

   del myHandleArray[1:3]
```
However, we do not support setting the content via a slice as this would
become too complicated and is likely never needed.

Use ROOT_CXX_STANDARD if it is already defined by ROOT, otherwise preserve previous behaviour and deduct it from ROOT_CXX_FLAGS

- RootHistogramSink: avoid having a 'registry' for each instance,
  instead keep one shared constant global in an anonymous namespace
  so it is hidden from the linker
- JSONSink: use the fact that `ofstream` closes the corresponding file
  when going out of scope
- BaseSink: use `std::set` with dedicted comparison operator instead
  of `std::map` which saves a bit of memory
- MonitoringHub: avoid one level of indirection in the type erasure
  which will type-erased function arguments to be passed in registers
  instead of forcing them to be passed through main memory
- MonitoringHub: `m_typeIndex` is an invariant once constructed, and
  does not need a type-erased function to be determined 'on the fly'

Allows to use the hiveWhiteBoard and select the right TES.
Made it backward compatible in the sense that by default TES number 0 is used seemlessly when number of threads is 1.
If several threads are used however, an error will be raised if the store is not selected explicitely

Change `GaudiHandleArray` type from `list` to `MutableSequence` and
implement the storage as `dict`, which is guaranteed to be
insertion-ordered as of Python 3. This considerably improves the speed
of `append`.

`insert` is potentially a bit slower but that is rarely used.
