This should fix the error about an ambiguous template instantiation
for 'struct halco::common::detail::limits<
halco::hicann_dls::vx::v1::SynapseOnSynapseRow, void>' which isn't
triggered on newer g++s. We dropped support for old `v1` hardware; this
was planned anyways.

We can drop oppulance from `spack.yaml` as it is no top-level
dependency anymore.

(BSS-2 features embedded SIMD processors for plasticity and other use
cases. This prepares for the next pynn-brainscales update adding
some code-generation features.)

Upgrade oPPUlance (cross compiler for BrainScaleS-2's embedded "PPU" processor)

Importing torch yields an ImportError caused by some mismatch between
build options (distributed is enabled, but tensorpipe is not →
this seems unsupported → enable tensorpipe).
