Adding in debugging scripts to help visualize XY feature matching. Modified align_stack_xy to not throw errors, but instead maintain an error_log that can be reviewed later. When in production, we'll use that error_log to break the algorithm for human intervention.
Modified view_xy_matches to combine uncropped, unaligned tile pairs, draw features on both, then link those features for an entire section. All those pairwise images are saved to cahce. Removed draft files.
Included scripts to investigate XY alignment error and updated the scripts to render a total section. Small improvements to the view_xy_matches script so that images will be loaded.
Fixes for S2-W001 Sections 15, 20, 59, and 105 (treated as 104 since we skip section 103). Included a staple_border script to help add features, as well as some other simple diagnostic scripts within /debug.
XY alignment adjusted to remove bad features. Rough Z alignment step included by comparing overviews. Z alignment slightly tweaked.
