	GEQDSK (g-file) and Osborne p-file (kinetic profile) readers and writers.

Functions
	_cocos_params (cocos_index)
	Return COCOS sign/exponent parameters for a given COCOS index.
	_crop_at_xpoint (seg, R0, Z0)
	Crop an open separatrix contour at the X-point to produce a closed LCFS.
	_detect_xpoint_angle (R, Z, R0, Z0)
	Detect the X-point angle on a separatrix contour.
	_flux_geometry (R, Z)
	Compute geometric properties of a single flux-surface contour.
	_read_geqdsk (filename)
	Parse a GEQDSK (g-file) into a plain dict.
	_read_pfile (filename)
	Parse an Osborne p-file into an OrderedDict.
	_resample_contour (R, Z, npts=257, periodic=True)
	Resample a closed contour to npts equally-spaced-in-arc-length points.
	_resample_contour_theta (R, Z, R0, Z0, npts=257, theta_xpt=None)
	Resample a closed contour to npts equally-spaced-in-angle points.
	_select_main_contour (segments, R0, Z0, sigma_RpZ, sigma_rhotp)
	Select the main closed contour encircling the magnetic axis.
	_trace_contours (R, Z, PSI, levels)
	Extract contour lines of \(\psi\) at given levels using contourpy.
	_write_fortran_block (stream, values)
	Write values in standard GEQDSK format (5 per line, 16 chars each).
	_write_geqdsk_to_stream (g, stream)
	Serialise a raw g-file dict g to an open text stream.
	_write_pfile (profiles, filename)
	Write an OrderedDict of profiles to an Osborne p-file.
	read_geqdsk (filename, cocos=1, nlevels=None, resample="theta", extrapolate_edge=True)
	Read a GEQDSK file and return a GEQDSKEquilibrium object.
	read_pfile (filename)
	Read an Osborne p-file and return a PFile object.
	write_geqdsk (g, filename)
	Write a raw g-file dict to filename.
