Preserve window size and position, also get and set

[michael-dewar]

This PR will preserve the size and position of the window when you open the xlsx in Excel. There are also functions to set and get directly.

Hi @michael-dewar , looking good. Just minor lintr issues and I'd like to see a test for this as well.

[michael-dewar]

I fixed the linter issues for the code I changed. I mostly avoided changing the other sections because I wasn't actually sure if the & vs && change made a difference compared to what was intended.

I also added tests.

Thanks, the other changes should be in the development branch
