Deposit problems with topology beneath

[Tom7Kimi]

With the new version of xsection we face problems with the deposit function on topography. We get the following error message:
std::bad_alloc in Region::merge

Should we avoid deposit later in the code?

With the old xsection it works fine.

Thank you very much!

The fix is ready and will be released with version 1.3
