This feature allows triggering the execution of the `build_action` command specified in
the `.ini` file when adding `build: true` to the frontmatter of the modified file. Upon
detecting this tag, the specified command will be executed automatically, facilitating
the automation of build processes in response to specific file modifications
Added support for specifying multiple correlated directories for both the watcher and the
destination. The `watcher_dirs` and `hugo_dirs` variables now accept a list of directories
separated by `:` in the configuration file. Each directory in `watcher_dirs` corresponds
to the directory in the same position in `hugo_dirs`.
This enhancement allows for greater flexibility and customization when monitoring and
processing files in different directories.
