FEATURE: Simplify the validity joins with dplyr::join_by. #169
Description
Describe the feature
When filtering the validity periods in diseasystore, we often have to copy the dates to the remote connection and then filter using an inner_join with an sql_on argument.
This syntax is more confusing than the new dplyr::join_by() syntax for the corresponding joins.
An example of the bad syntax can be seen in the simulist_age FeatureHandler in #162 which is confusing for the user.
SCDB has a pull request open for allowing dplyr::join_by() in its joins (ssi-dk/SCDB#156)
Once released, we should implement in diseasystore to simplify the code
What use will this feature have?
