SIS 5 v5.9.3

[kjerram]

Early field experience with SIS v5.9.3 suggests significant improvements to swath artifacts and outliers that have been noticed with the latest generation of EM multibeam systems.

Users are strongly urged to upgrade to 5.9.3 (https://www.kongsberg.com/maritime/support/document-and-downloads/software-downloads/ - user login required) and verify with Kongsberg support that all other firmware is up to date.

Many thanks to Saildrone for rapidly iterating with Kongsberg support and providing 'before' / 'after' examples to highlight the improvement.
