Support splitting files with --- / added tests

Added some tests to verify that you can now split your files with --- to
join multiple queries into a single file. This could be for if you have
two separate regexes to run or even two sources you want to run the same
query against.

Example file:

```example.conf
query=.*example.conf$
source=/path/to/example/
target=/path/to/dest/
---
query=.*different.csv$
soruce=/path/to/different/
target=/path/to/dest/
```
