Feature

Improve 'not divisible' error message for fixed record length files.

Example

Now:

There are some files in s3:/test that are NOT DIVISIBLE by the RECORD SIZE calculated from the copybook (100 bytes per record). Check the logs for the names of the files.

Should be:

File s3:/test/file.dat size (123123 bytes) is NOT DIVISIBLE by the RECORD SIZE calculated from the copybook (100 bytes per record).
