Updated ffv parser from PDF to default

[nicolaibvm]

Summary

After having FFV adding next schedule to affaldonline, I found that PDF is not the right parser, but comparing to the output of assens it should be default. My tests with the regex seems to correspond.

I think I have done this incorrectly. I am not used to doing this. I made a commit (push/pull?) of this code earlier. It didn't work. Therefore I have worked on getting the info on the homepage. The data is now there but I cannot remember how I committed the last time. If this is totally wrong, please delete this. I can't seem to do it myself. I apologize for any inconvenience.

I also guess that if this is accepted, that the doc/source/affaldonline_dk.md, should be updated to reflect the changes. I will of course do this and try to do it the right way, this time.
