This function allows an existing level to reorganize (or discard)
its \a disk content. It is typically implemented by TLevelWriters
that support <I> random access writing <\I>, which can therefore
write new frames on top of an existing level.

This function requires that frames present on disk \a and in the
table be remapped, while frames on disk \a not in the table be
\b deleted. Eventual frames present in the table but not on disk
are ignored.

The default implementation provides renumbering for standard
Toonz multi-file level types (levelName.####c.ext), and does nothing
if the specified path is not compatible with the multi-file format.
