Edge Correction

[michaelkiper]

Overview

This PR is to add in the edge correction according to Francisco's code.

It's fairly straight forward. The static.yml file defines a new field for edge correction where there's a new key-value pair that's the "name-of-file": [list, of, left, edge, indices]. Then during the static processing portion, it'll perform an in-place correction of the magnitudes of the edge discontinuities.

To note: the edge correction will adjust the preceding LEFT side of the edge discontinuity. AND moreover, the preceding left spectra magnitudes will be cumulatively scaled as there are more edges to correct.

Pull Request Overview

This PR adds edge correction functionality to handle spectral data discontinuities by scaling the left side of edge indices to match adjacent magnitudes. The correction is applied cumulatively when multiple edges are specified, with each edge's left portion being scaled based on the ratio between adjacent wavelength band values.

Key changes:

• New left_edge_scale function that performs in-place magnitude correction on spectral data
• Integration of edge correction into the static data processing pipeline
• Configuration support for specifying edge indices per dataset class
