Explore possibly of setting a series of user shortcuts for RStudio

The idea here would be some function:

`dipr::create_shortcuts` which would then populate a file here: https://support.rstudio.com/hc/en-us/articles/206382178-Customizing-Keyboard-Shortcuts

Ideas for shortcuts:
`dipr::insert_bcgov_apache_header`
`styler::style_selection`
`drake::r_make`

Start with the proposed dipr::create_shortcuts function and read the linked RStudio keyboard-shortcut customization article. Determine whether the package can populate the referenced file, which shortcuts should be supported, and what behavior would define completion; the issue does not identify local files or tests.
