Lazily *regenerate* the underlying tvbs.
The "bottom-level" tvbs would be regenerated by reading packet data from the file.
However, there might be "intermediate-level" tvbs that do *not* contain data directly fetched from a file; instead, the data might have been decompressed, or decrypted, or de-encoded from base-64, or otherwise processed. Consider a packet reassembled from 3 lower-leel chunks, the first of which came from a base-64 decoding of still lower-level data reassembled from 5 even lower-level decrypted packets....
