Error loading DSM's sab files

[radovanma]

I'm trying to import the sab files contained in RSDOC Design Spark Mechanical (v4 or V5) documents using the InventorLoader plugin (as native or convert to STEP), but some errors appear and the sab file won't open.
I tested this on FreeCad versions 0.20.2 and 0.19
You can "mine" the sab file by renaming the .rsdoc file to a .zip file (TestFile.zip\SpaceClaim\Geometry\part1bodies.sab).

Here is the FreeCad Log:

The sab version is 28 (v4) and 29 (v5), which is not supported by this plugin

Hello,
Ansys hat incorporated a 'strange' feature when saving the ACIS information in binary files.
normally it is "body ... #" here we have "body%UINT32 ..." and I don't understand the meaning of the 32Bit integer value.
It looks like, that the number is the number of the entity.

I think I found a way to read the format - please check out latest version.
