Fixed Pydantic sphinx autodoc issues on Github deployment

Removed all Python pipeline item (processor, reader and writer) classes imports except for those required by the Pydantic sphinx autodoc bot from all (sub)package level __init__.py files. This benefits the overall setup speed of running any workflow, but does result in a change in how processors, readers and writers are called from the pipeline.yaml. Previously, they could be called from the packet level, going forward they should be called from the module level. For example:

    ⋮
 - common.YAMLReader:
      filename: energy_calibration_result.yaml
      schema: edd.models.MCAEnergyCalibrationConfig
 - edd.MCATthCalibrationProcessor:
    ⋮
 - common.YAMLWriter:
      filename: tth_calibration_result.yaml
      force_overwrite: true

Should be modified to:

    ⋮
  - common.reader.YAMLReader:
      filename: energy_calibration_result.yaml
      schema: edd.models.MCAEnergyCalibrationConfig
 - edd.processor.MCATthCalibrationProcessor:
    ⋮
 - common.writer.YAMLWriter:
      filename: tth_calibration_result.yaml
      force_overwrite: true

Note that for now the code will stay backward compatible with the old style pipeline.yaml files. However, it may become deprecated at a future time, so it is strongly suggested to update pipeline.yaml files to the new style going forward.

What's Changed

EDD

• Changed the default minimum d-spacing to 0.35 in various EDD configs and processors
• Added HKL and fitted peak info to the NeXus output
• Added HKL based strain results to strain analysis NeXus output
• Added HKL strains object for the unconstrained fit results in the strain analysis NeXus output file

GIWAXS

• Added presample intensity correction
• Implemented wedge correction using native pyFAI methods

SAXSWAXS

• Implemented the full SAXSWAXS workflow in CHAP replacing the former SAXSWAXSWorkflow codebase

Tomo

• Added presample intensity correction
• Split the former combined Tomo workflow processor into individual ones aligned with the workflow steps and conforming with the * CHAP processor/reader/writer conventions
• Updated the tomography test cases with these updated processors
• Modified the tomography center axis finding tool and created a GUI for interactive center finding

CLI

• Added --regex CLI option for matching sub-pipeline names
• Added --batch CLI option for running sub-pipelines as separate parallel processes

Fitting

• Added Lorentzian and PseudoVoigt models to regular and multipeak fitting
  (for use in EDD, but also available for any other workflow)

Documentation
