Simplify type when nesting ShiftedDynamicMultiIndex

See merge request !395

This adds an overload for `shiftedDynamicMultiIndex()` that
ensures that shifting a multi-index twice will not produce
a nested `ShiftedDynamicMultiIndex` but add the offsets.
While the behaviour of the resulting multi-index is the same,
the type is simplified which eases reading error messages
and debug output, because you get
`ShiftedDynamicMultiIndex<Index,3>` instead of
`ShiftedDynamicMultiIndex<ShiftedDynamicMultiIndex<ShiftedDynamicMultiIndex<Index,1>, 1>, 1>`.

typo: TreeDate -> TreeData

See merge request !394

Thankfully we don't have to deal with calendar dates in DUNE.

Install two additional headers

See merge request !391

The headers globalvaluedlocalfiniteelement.hh and raviartthomasbasis.hh
were not installed.  This was apparently an oversight.

Remove updated toolchains from gitlab-ci

See merge request !386

Implement operator() for DiscreteGlobalBasisFunction

See merge request !387

This does a hierarchic search over the elements.  It may hence
be very slow.

Adapt changelog after release

See merge request !385

Update the list of authors

See merge request !383

Update dune.module file after 2.9 release

See merge request !382

[cmake][python] Replace deprecated dune_python_install_package

Python: Add grid property to DiscreteFunction

See merge request !377

This is necessary for the current plot functionality in the dune-common
Python bindings.

A test extracting the grid is also added.

.gitlab-ci.yml: add "duneci" tag to spellcheck

See merge request !376

The shared runner might not pick up the job otherwise.

Add missing include / use std::invoke_result

Clang master (futur 15) warns about it

Caused compilation error in DuMuX

[CI] Run the 'codespell' tool

See merge request !371

This will warn about misspellings in the source code.

The new namespace is dedicated to implemenation details that should
not be generically ignore by doxygen, e.g. because the contained
classes are mixins whole members should show up in the documentation
of the derived class.

This mixin base class does not do anything with this member.
Hence it's easier to not pass it as template parameter, but
directly store it in the derived class.

* Unify algorithm for mapping shape function range and coefficient
  to the function range. Effectively the new implementation produuces
  the same results but is much easier to understand and describe.
* Move `DiscreteGlobalBasisFunctionBase` to implementation name space.
* Factor out access to nodeToRangeMap` and assignment of different
  container types.
* Uniformly initialize all vectors/coefficients with `istlVectorBackend(c)=0;`
* Don't use `operator+=` when we actually assign a zero-initialized value.
* Swap loop order. Having the statically sized loop inside it is more
  likely to be unrolled.
