890327b381 the returnvalue of the diskio.load() function family now is just the last load address+1 (like kernal's LOAD routine).
This fixes the inconsistent attempt to calculate a size, just let the caller do this if required.
Added a small helper function in cx16diskio to do this for loads that span multiple banks.
