Tritech image data handling and file i/o

This repo contains classes which can unpack Tritech Gemini ECD and GLF files.

Note that these functions are written in pure Java. Tritech do make a C++ SDK available which may be more stable and can handle the full file format. What I've done here is a bit of a 'hack', may only work with the files I have collected, and may not be at all future proof.

Motivation is primarily to be able to efficiently read data into PAMGuard (www.pamguard.org) for display. This package is deliberately kept separate from all PAMGuard structures so that the classes can easily be called from other languages, e.g. Matlab.

Also included are classes which can take the rectangular data frames from sonar images and render them into a fan shaped matrix of data for display. It is quite likely that this does NOT use the same transformations going from rectangle to fan as the Tritech SeaTec and Gemini software use.
