* This fixes#188
* In App.tsx
- import LoggingLevel from sdk
- add [logLevel, setLogLevel] useState with value of type LoggingLevel initialized to "debug"
- add useEffect that stores the new logLevel in localStorage as "logLevel"
- added sendLogLevelRequest function that takes a level argument of type LoggingLevel and sends the appropriate request. It calls setLogLevel when done, to update the local UI
- pass logLevel and sendLogLevelRequest to Sidebar component as props
* In Sidebar.tsx
- Import LoggingLevel and LoggingLevelSchema from sdk
- add props and prop types for logLevel and sendLogLevelRequest and loggingSupported
- add Select component populated with the enum values of LoggingLevelSchema, shown only if loggingSupported is true and connectionStatus is "connected"
