[BUG] Unable to parse large YAML configuration file

[ZeLonewolf]

When loading a large YAML config file, planetiler throws the following exception:

Exception in thread "main" org.snakeyaml.engine.v2.exceptions.YamlEngineException: The incoming YAML document exceeds the limit: 3145728 code points.

This occurred for me when trying to load a 7.5mb Yaml file. Since the size of the input Yaml is known, it should be possible to get the SnakeYaml input filesize limit to match the size of the input file:
