Fix issue with incorrect x and y for rotated key

[kevin-wells]

kle-serial behaves differently to keyboard-layout-editor for rotated keys, for example the E key in the default Atreus layout.

Changed include a test to replicate the problem, and a fix which does the same thing as keyboard-layout-editor.

I also added es5 and es6 to libraries because otherwise npm run build would not work for me.

Tested this out with my project, works for me.

@kevin-wells I have a differently coded fix for this. Would your PR benefit from any of my code?

@chr11031 Is this fixing a bug e.g. a layout that works with keyboard-layout-editor but not kle-serial? I've been treating https://github.com/ijprest/keyboard-layout-editor/blob/master/serial.js as the specification.

[chr11031]

@kevin-wells That is correct. In rendering KLE data parsed from KLE-Serial I found these changes necessary to address the rotation issues I believe your PR/Issue is covering.

I saw that you might be working on something similar to my challenge so I'm sharing these changes with you. I shared it in the hope that maybe it would prove useful to you. If I'm misreading things though or it is not relevant to your interests, no loss in ignoring my contribution.

@ijprest is this something we can get merged and published to npm? Came across this issue as well with an Alice layout.

Also tested the change and it works for my case as well, FWIW. 👍
