we used this library solely to interpret the answer of an HTTP web
server as JSON and find a particular value using a path expression in
the HTTP power meter implementation.
since we ran out of flash memory on non-S3 ESP32, we need to cut some
corners. removing FirebaseJson is the last low-hanging fruit that we
currently know of. we can get rid of it by using ArduinoJson (which is
already integral part of the firmware) and implementing a custom logic
to extract a value based on a path expression.
other than the FirebaseJson path "finder", the new implementation
only knows how to access sub-keys delimited by a forward slash. in
particular, accessing array members is not supported any more. I am
hoping that this is simply not an issue. if so, we will have users
complaining and we can add this functionality in a later release.
