BUG - Add SWE DELTA_* uncertainty pointers to metadata

[greglucas]

Description of the issue

The SWE L2 data files are missing DELTA_PLUS_VAR and DELTA_MINUS_VAR pointers to the statistical uncertainty values in the file. Update the metadata configuration to add these attributes.

imap_processing/imap_processing/cdf/config/imap_swe_l2_variable_attrs.yaml

Lines 205 to 222 in 0d7eea6

	flux:
	CATDESC: Number flux organized by energy (eV), spin angle, CEM angle
	DEPEND_0: epoch
	DEPEND_1: energy
	DEPEND_2: inst_az
	DEPEND_3: inst_el
	LABL_PTR_1: energy_label
	LABL_PTR_2: inst_az_label
	LABL_PTR_3: inst_el_label
	DISPLAY_TYPE: spectrogram
	FIELDNAM: Flux
	FILLVAL: -1.0E+31
	UNITS: 1 / (2 * eV * cm^2 * s * ster)

	VALIDMAX: 1.0E+9
	VALIDMIN: 0.0
	VAR_TYPE: data
	DICT_KEY: SPASE>Particle>ParticleType:Electron,ParticleQuantity:NumberFlux,Qualifier:Array

Should have both of those attributes that point to this variable name:

If I'm reading this right, it seems like the data is actually already there, and literally this is just a matter of modifying the YAML files. Can copilot handle this? Let's find out!
