Missing optional arguments in pdfinfo_from_bytes and pdfinfo_from_path

[magnurud]

Describe the bug
pdfinfo_from_bytes and pdfinfo_from_path does not have support for optional arguments -f and -l.

From the documentation:

−f number

Specifies the first page to examine. If multiple pages are requested using the "−f" and "−l" options, the size of each requested page (and, optionally, the bounding boxes for each requested page) are printed. Otherwise, only page one is examined.

−l number

Specifies the last page to examine.

Expected behavior
I would expect to be able to get info from several pages of the pdf.

If you can implement it that same way it is implemented in convert_from_path and convert_from_bytes I'd happily accept a PR: https://github.com/Belval/pdf2image/blob/master/pdf2image/pdf2image.py#L41
