Update documentation for Windows about patch-package

[ds300]

Thanks, this chimes with what I discovered while debugging #20 last night. I'll try that out and update the README if it goes smoothly.

Works like a charm! Would never have realised that you can control EOL characters for particular extensions with .gitattributes. Thank you 🙇

Thank you for patch-package 🙇
Maybe you should note, that the .gitattributes work-around only works if people actually use Git and that the files need to be checked out, as the conversion happens during checkout (i.e., if the files are already there, they need to be checked out again).

Good idea, I'm noting that, as well as adding a contextual error message to point people in the right direction when patch application fails for this reason.

I've updated the README now to reflect the changes you suggested. Thanks again! Really big improvement!
