Feat: Add support for multiple correlated directories

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.

 Configuration runs in `~/.config/obs2hugo/obs2hugo.ini` or `~/.config/obs2hugo.ini`, something like this:
 
 ```ini
-watcher_dir = /Users/johndoe/vaults/obsidian/posts-hugo
-hugo_dir = /Users/johndoe/code/hugo/src/content/posts
+watcher_dirs = /Users/johndoe/vaults/obsidian/microposts-hugo:/Users/johndoe/vaults/obsidian/posts-hugo;
+hugo_dirs = /Users/johndoe/code/hugo/src/content/posts:/Users/johndoe/code/hugo/src/content/microposts
 ```
 
+Note: The `watcher_dirs` and `hugo_dirs` variables must have the same number of elements, taking into account that `:` acts as a separator. They are correlated so the first element in `watcher_dirs` corresponds to the first element in `hugo_dirs`, the second element in `watcher_dirs` corresponds to the second element in `hugo_dirs`, and so forth.

 1. Clone the repository to your local machine.
