Issue DM-1383: Investigate deblending in one band followed by using the resulting templates in all bands
(See also [HSC-1025| https://hsc-jira.astro.princeton.edu/jira/browse/HSC-1025]) One poor-man's approach to deblending multiple bands and visits is - Deblend in one band (or a combination, e.g. chi^2 band) using an SDSS-like algorithm that produces templates for each child - Take the templates (or possible model fits to those templates) and use them to deblend the objects in all other bands It will probably be necessary to include undetected objects in this fit (cf. [HSC-1023|https://hsc-jira.astro.princeton.edu/jira/browse/HSC-1023]), using point-source models. Note that this does not allow for the different seeing in each band. This is not obviously catastrophic for reasonably wide blends as the total flux in each pixel is conserved, and if only one template is important near an object's centre the exact form of the template is unimportant.
