Release: https://github.com/openmaptiles/openmaptiles/releases/tag/v3.13.1

Changes: openmaptiles/openmaptiles@v3.13...v3.13.1

Steps to upgrade:

• Change 3.13 reference to 3.13.1 in Generate.java and scripts/regenerate-openmaptiles.sh README.md and planetiler-basemap/README.md
• run scripts/regenerate-openmaptiles.sh
• Go through the changes to each layer:
  • yaml file changes were applied automatically by the script, you might just need to add/update tests in planetiler-basemap/src/test/java/com/onthegomap/planetiler/basemap/layers based on what changed
  • sql file changes should get reflected in java code/tests in the corresponding layer in planetiler-basemap/src/{main,test}/java/com/onthegomap/planetiler/basemap/layers

I find it's easier to look through the consolidated file diffs instead of individual changes, in case a change was made then reverted/changed later - but sometimes you do need to go back to a PR to understand the intent of a change.
