Wrapping up for now

I think things are in good shape, so setting aside until @stephpenn1 and I talk in a couple weeks.

The dashboard code in this new repository:

Dependencies and memory

• Has lower memory usage, and is faster, than the original #16
• The repository is 95% smaller and has fewer package dependencies
• We now use renv for dependency management https://github.com/COMPASS-DOE/TEMPESTdash/commit/234198b0f8607839b533fc9cd4804733e7c42978 - this ensures consistent package versions are always used

Organization

• Puts a lot of support code into R/ #10
• Uses Shiny modules for some (but not all) code #7 #6
• Fixes a number of bugs and annoying messages
• Improved and expanded commenting throughout

Tests and bugs

• Adds extensive test code #23 #4 etc. There are three levels of Shiny tests: unit tests, module tests, and app tests
• Adds continuous integration, so tests run when a PR is opened to master; a badge in the README file shows test status

Functionality changes

• Allows the dashboard to have a flexible datetime—i.e., it can be set to a past date. This is important for testing, but also opens the door to let us skip back in time through user input #22
• All these changes are backend; the user-facing UI is (almost) identical
