### Description
This PR improves the wording around the mysterious
`InvalidNullByteException`. The exception occurs when the strings that are
added to the frame contain the 0x0000 byte which is internally being used as a
delimiter in the case of a string column. The current use case for the frames
is MSQ exclusively, and this error will only be generated if the ingested
external data contains hidden null bytes, which in most cases can safely be
sanitized.
