romancal.scripts.static_preview is causing downstream testing errors

[WilliamJamieson]

The following lines are causing downstream testing errors

romancal/romancal/scripts/static_preview.py

Lines 6 to 15 in 3fbf571

	from typing_extensions import Annotated
	try:
	import typer
	from stpreview.downsample import downsample_asdf_to
	from stpreview.image import north_pole_angle, percentile_normalization, write_image
	except (ImportError, ModuleNotFoundError):
	raise ImportError(
	'SDP requirements not installed; do `pip install "romancal[sdp]"`'
	)

This is because typing_extensions is an external dependency which is not listed in the pyproject.toml file and stpreview is not a standard install. This occurs because when running the romacal tests relative to changes in another library, the exemption of romancal.scripts from pytest recursing in:

romancal/pyproject.toml

Line 118 in 3fbf571

'romancal/scripts',

cannot be respected by a third party package executing the romancal tests.
