3. Adds a type change utility for append data keys in lib_tool …

   Does this by adding a cpp layer functionality to overwrite append data
   keys. And using a read + type change + overwrite in the python layer.
   
   More specifically this change involves:
   - Using a `LocalVersionEngine` instead of an `AsyncStore` as library
     tool state
   - Exposing some more python bindings to allow iteration over `APPEND_DATA`
     keys with the library tool
   - Allow using normalization in library tool to allow overwriting append
     data keys with a custom dataframe
   - Provide the type change functionality by reading a dataframe, changing
     its type with pandas and overwriting it
   - Adds an elaborate test to verify iterating and reading append data
     linked list is fine with various overwrites.
