Making FPDF.output() x100 time faster by using a bytearray buffer
There is a detailed article explaining why this is faster: https://www.guyrutenberg.com/2020/04/04/fast-bytes-concatenation-in-python/
On a document I'm working on with over 12 000 pages, thanks to this patch the output generation passed from taking 20 minutes to 2 seconds.
I added a commit that also improves the performances of internal calls to ._out() (_e.g. inside FPDF.image()),
using the same approach.
This new commit also introduces DEBUG logs indicating the sizes of the final doc sections.
Can confirm that this works wonders, master version did not finish within 20 minutes for 1040 pages of images, this did it in 5 seconds. Cheers! Hope it gets added soon.
I dont think anyone is adding things to this project, but i just released a new version of my fork of it due to a request to support python3.9.

I was planning to release a pyfpdf2 lib on Pypi before the end of the year, but I realize someone has already done that ! :D
@alexanderankin, do you think other commits from my fork could be merged into yours ? cf. https://github.com/Lucas-C/pyfpdf#pyfpdf-fpdf-for-python
I'd be willing to contribute to a maintained fork of pyfpdf :)
i doubt it but i can take a serious within this week. the very first commit i did was style, so a clean rebase is not likely.
