When writing data to a transparent or linear fixed (record oriented)
and the data to write exceeds the record/file size, then the UICC will
respond with an error "6700: Checking errors - Wrong length"
In particular when the data is supplied as a JSON object and not as a
hex string, it may not be immediately obvious to the average user what
the problem actually is.
Let's check the record/file size before writing the data and raise an
exception in case the data excieeds the record/file size. Let's also
print an informative string message in case the data length is less
than the record/file size to make the user aware of unwritten bytes
at the end of a record/file.
