Reduce duplication 1

[CBroz1]

Description

This is a tidying PR that aims to (a) merge existing fully duplicated functions, and (b) increase similarity across functions that will be merged in future PRs. The latter is included as an initial step to make sure what I see as similar is intended as such. This includes cases where the newer version of something was improved without giving the same stylistic edits or additional functionality to the old version.

This partially addresses #977, per checklist in most recent comment.

• common_ephys.py, B: add spacing/line breaks to reflect updated version
• common_position.py, B: Add default value for unused variable.
• decoding/utils.py, A: Common location for _get_peak_amplitude. Updated V0 to pass the waveform extractor instead of waveform
• decoding/v0/
  • A: Migrate funcs to V0 utils
    • discretize_and_trim
    • get_time_bins_from_interval
    • make_default_decoding_params - required some additional control-flow for cpu/gpu and clusterless/spikes.
  • B: Add comments/spacing to get_X_data
• decoding/v1/
  • clusterless, B: add track_graph and time_slice params/functionality
  • migrate out subfunc for get_orientation_name
• linearization/v1/main, B: make table definition comments/spacing like V0 def
• position/v1/dlc_utils, A: import funcs from common
• ripple/v1/ripple, A: import func from prev version
• spikesorting_merge, B: add smoothing sigma param with default
• other Bs: Adjust to look like match
  • spikesorting_curation
  • spikesorting/v1/curation
  • spikesorting/v1/recording
• spikesorting/utils.py, A: Extracting core logic of set_group_by_shank into a function that returns insert candidates for parent functions to run. Internal logic otherwise the same
• spikesorting/v0/curation_figurl, B: Updated to reflect V1 version that uses comprehension over for loops
• spikesorting/vX/artifact, B: Reflow of docstring, migrate variable reassignment to within ChunkRecordingExecutor call.

Other changes:

• decoding_merge: removed unused import
• decoding/v1/core: remove reference to undefined variable in error message
• See comments about...
  • linearization: potential removal of get_networkx methods
  • spikesorting_merge: lack of a check for ndim==1 compared to alternate version
