podcastfy won't take raw text as content file.

[VincentJGeisler]

When generating podcasts with knowledge bases that are just pure text, eg --url somefile.txt, the program gets confused and acts as though you have sent it a --file flag and tries to load the content of the text file as a file full of url's

ive confirmed that if I convert the raw text file to pdf, then it works as expected with --url somefile.pdf.

here is a dump of an attempt to use a raw text file as a url input.

python -m podcastfy.client --url file:///tcconv.txt --transcript-only
