validate_upload: Validate Case Assignment Upload
In jesse-smith/covidassign: COVID-19 Case Assignment for SCHD

validate_upload() validates that all assigned cases were uploaded. By default, it archives accepted and rejected cases and notifies relevant parties of the status. Note that, unlike validate_assignments(), a notification is sent even if all cases are uploaded correctly.

validate_upload(
  .data,
  archive = TRUE,
  notify_to = c("Jesse.Smith@shelbycountytn.gov", "Karim.Gilani@shelbycountytn.gov"),
  cnd = c("warning", "error"),
  date = attr(.data, "date")
)

`.data`	Upload data from `upload_assigments()`
`archive`	Should accepted and rejected cases be archived?
`notify_to`	Email addresses to notify of case assignment. Set to `NULL` to disable notification.
`cnd`	Should rejected cases trigger a warning or an error?
`date`	The date to use in notification
