Cannot use ScanCode.io fully as a library

[pombredanne]

In a few places, scancodeio settings are used instead of django.conf. In MatchCode, this makes this super hard as the scancode.io settings will be imported even if not desired.

• scancode.io/scanpipe/pipes/federatedcode.py

  Line 37 in 2309019

  from scancodeio import settings

• scancode.io/scancodeio/context_processors.py

  Line 26 in 2309019

  from scancodeio import settings

• /etc config takes precendence over local config #240

Actually, scancodeio/ should NOT be part of the library and wheel at all

scancode.io/MANIFEST.in

Line 16 in 2309019

graft scancodeio

Actually, scancodeio/ should NOT be part of the library and wheel at all
but ScanCode.io proper should have it part as part of its wheels.
Therefore, I think we need a separate package, like we did with the pipeline, something like a scancodeio-toolkit-pyproject.toml or a scanpipe-pyproject.toml:

[build-system]
requires = ["flot"]
build-backend = "flot.buildapi"

[project]
name = "scanpipe"
version = "0.2.1" <== use same version as main SCIO
description = "ScanCode.io Scanpipe library."
license = { text = "Apache-2.0" }
readme = "README.rst"
requires-python = ">=3.9"
authors = [ { name = "nexB. Inc. and others", email = "info@aboutcode.org" } ]
keywords = [
    "open source",
    "pipeline",
    "scancode",
]

includes = [
    "scanpipe/*",
    "scanpipe/*",
]
metadata_files = [

    "NOTICE",
    "README.rst",
]

and we should also automate the releasing and add some smoke tests to make sure the library is functional
