Issue DM-2778: HSC backport: allow for use of Approximate model in background estimation
This issue involves transferring changesets from the following HSC issues: - [HSC-145|https://hsc-jira.astro.princeton.edu/jira/browse/HSC-145] Investigate approximating rather than interpolating backgrounds - [HSC-1047|https://hsc-jira.astro.princeton.edu/jira/browse/HSC-1047] Background object cannot be loaded with butler - [HSC-1213|https://hsc-jira.astro.princeton.edu/jira/browse/HSC-1213] Set background 'approximate' control settings when background control is created. - [HSC-1221|https://hsc-jira.astro.princeton.edu/jira/browse/HSC-1221] tests failing in ip_diffim - [HSC-1217|https://hsc-jira.astro.princeton.edu/jira/browse/HSC-1217] Verify backgroundList IO works properly when Approximate is enabled in background control - HSC JIRA The Approximate (Chebyshev) approach greatly improves the background subtraction around bright objects compared with the interpolation scheme currently in use (which over-subtracts near bright objects).
