v0.9.4

• Released snowflake connection and connectors.
• Changed ordering of datasets to be more intuitive (topologically first for CDISC datasets only and then according to input datasets order).
• When closing a teal app (ending a user shiny session), all DataConnections will now try to close their connections.
• Added ADHY keys to configuration file.
• Extended the filter_spec function: the parameter choices is no longer mandatory (the function will take all possible choices by default) and the vars parameter additionally accepts the choices_selected and allows to change the variables for filtering using the UI elements in the encoding panel.
• Cleaned up imports in the package.
• Modified value_choices function to handle edge case when "NA" and NA values exist in the character column that choices are derived from.\
• Fixed issue with cloning Callable class.
