This commit also fixes the application of the empiricalShift in the
tracking algorithm. It is now applied the same way as the offsets,
namely: TOA + -1 * empiricalShift

chore: Replaced "Plot residuals" checkbox with value of calculated/measured soundspeed in track parameter panel

The soundsource combinations table now has a "use" boolean for enabling/disabling the combination during tracking.

Added a new column to the tracking parameter panel ReferencePositionEnd. Adjusted the tracking algorithms accordingly.

Added first version of the new backward tracking method. It is now possible to use interpolation methods as well.

Integrated the empiric_offset and empiric_drift parameter of the float, Changed copy offsets layout.

The etopo file must be downloaded separately and linked as parameter
etopo in the files section in artoa.ini file.

Updated versioning system. Artoa now checks if your loaded interim file is compatible to the artoa version you are using.
