Merge pull request 'pdf-by-filename' (#28) from pdf-by-filename-#27 into main

Implemented PDF dir:

+ now you can set a `pdf_path` variable in the config and throuch the CLI flag `--pdf-dir`
+ this dir will be searched recursivley for PDF files which mathc a citekey from the used `.bib` files and connects with them
+ every entry can have multiple PDFs with the citekey-basename in different subdirs
+ the bibfile itself will not be altered
+ additionally, i rewrote the internal popup code for easier contribution
