Functionalizer

==============

Fixes:
- The `SynapseReposition` filter did not parse the recipe correctly. See
also FUNCZ-257_.
- The `nrrp` parameter to synapse generation is read as a floating point
value again. See also FUNCZ-258_.

Changes:
- The SONATA input will now create the field `synapse_id`, hence
deprecating the `AddID` filter.
- The plotting utilities have been removed as our ability to obtain
performance data has been crippled. See also FUNCZ-244_.

==============

Fixes:
- The parameter `nrrp` was off by one.

==============

Changes:
- Added a `AddID` filter to be able to process SONATA without the
`synapse_id` field. Also skip the generating the `axonal_delay` field
if `distance_soma` is not present in the input. See also FUNCZ-212_.

Fixes:
- Multi-population support had source and target populations swapped

==============

Changes:
- Added `p_A` and `pMu_A` to allowed parameters in `mTypeRule`. See
FUNCZ-242_.
- Added support for additional positions in the TouchDetector output. See
FUNCZ-236_.

Fixes:
- More robust filter loading

==============

Changes:
- Process `uHillCoefficient` and `gsynSRSF` attributes of
`SynapseClassification`. See FUNCZ-238_.
- Added filters `DenseID` to compress the ids of gap junctions (to be run
before `GapJunction`, and `GapJunctionProperties` to set the
conductance of gap junctions. These filters are active by default when
running with `--gap-junctions`.

==============

Changes:
- Split of repositioning of synapses into a separate filter. See
FUNCZ-226_.
- Fix branch type matching in `TouchRules`. Allow `axon` to be matched,
and do no longer match `axon` values when using the `dendrite` value.
This should not have a user impact, as the default `TouchDetector`
touch space is axon-dendrite connections. See also FUNCZ-216_.
- Activate spine length filtering if recipe component is present.
