Add profile for Kindle Paperwhite 5 (Signature Edition)

[Einlar]

Adds a profile for Kindle PW 5 (also known as "Signature Edition") with a 6.8 inch display. The resolution (1236x1648) was found from Wikipedia.

This also adds the changes from two other PRs (#393 and #331 ) for convenience.

Full installation procedure

I assume you have git and Python 3 installed. I did this on Windows 10, but it should work also on Linux.

Clone the repo:

git clone https://github.com/ciromattia/kcc
cd kcc

Merge with this PR:

git fetch origin pull/404/head:kindle_signature
git checkout master
git merge kindle_signature

Install

pip install -r requirements.txt
python setup.py install

Launch
python ./kcc.py

You may need KindleGen.exe. Steps for adding it can be found here (as pointed in the issue #402).

I followed your full installation procedure. Once I click the Convert button in KCC I get the following error message in a Windows Error popup. Any idea what's going wrong?

Error during conversion C:\Users\Danny\Desktop\File.cbz:

One of workers crashed. Cause: 'float' object cannot be interpreted as an integer

Thank you for the PR, let's hope the owner can release a new version with this 🤞
I have tried myself to run in mac with no success. Every time I run it, it cannot locate KindleGen and 7lib (kindlegen path already added as an env var and even in $PATH) while the latest release binary works fine for me. I could not build a new binary either. Let me know if I can do something else to fix it.

Thanks, works fine on Linux.
Kindlegen needs to be copied in /usr/local/bin .

In Windows i have the same problem as @DannyEnsink .

[darodi]

Thanks for your pull request.

There was a small problem with it.
Panel view 4/2/HQ doesn't work with it. Double tap does nothing.

I created a new pull request with an additional commit to fix it.

see #405

[DannyEnsink]

Does this also fix the issue @comicrocharly and I (see #404 (comment)) are having on Windows?

@DannyEnsink

I haven't been able to reproduce your error, but you can maybe try replacing this line
self.image = ImageOps.autocontrast(Image.eval(self.image, lambda a: 255 * (a / 255.) ** gamma))
with
self.image = ImageOps.autocontrast(Image.eval(self.image, lambda a: int(255 * (a / 255.) ** gamma)))

in \kindlecomicconverter\image.py line 261

[DannyEnsink]

That worked, thanks. I'll update this comment when I verified the results on the Paperwhite 5.

EDIT: Tested with the generated .mobi from KCC and put in the documents folder on the Paperwhite 5. Works great!
