Add pdfminer to requirements - and bug report.

Add pdfminer to requirements.

• In requirements.txt pdfminer isn't listed.

When running PDF-to-Text option I get

TypeError: TextConverter.__init__() got an unexpected keyword argument 'codec'

Full Error:

@Theblackcat98 The error you're encountering with pdfminer is due to changes in the pdfminer.six library, where the codec argument is no longer accepted by the TextConverter class.
Try out these steps, and let me know, if it works

1. update the req.txt file with inclusion of latest version pdfminer.six, through pip install pdfminer.six
2. Modify the text-to-speech function:-
   Update the convert_pdf_to_txt function to remove the codec argument from the TextConverter initialization.

from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.pdfpage import PDFPage
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from io import StringIO

def convert_pdf_to_txt(path):
    rsrcmgr = PDFResourceManager()
    retstr = StringIO()
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, laparams=laparams)
    fp = open(path, 'rb')
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    for page in PDFPage.get_pages(fp):
        interpreter.process_page(page)
    text = retstr.getvalue()
    fp.close()
    device.close()
    retstr.close()
    return text

let me know, if it works
thanks
