A helper class for serializing and deserialization of the RNTuple binary format.
All serialization and deserialization routines return the number of bytes processed (written or read).
The serialization routines can be called with a nullptr buffer, in which case only the size required to perform a serialization is returned. Deserialization routines must be called with a buffer that is sufficiently large.
Deserialization errors throw exceptions. Only when indicated or when passed as a parameter is the buffer size checked.
