[jolivain]

The file is indented with 4 spaces. Some lines are incorrectly indented with TABs. This commit change those TABs to 4 spaces to fix the gcc misleading indentation warning.

Fixes:

src/cpp/automations.cpp: In member function ‘void rtosc::AutomationMgr::setSlotSubPath(int, int, const char*)’:
src/cpp/automations.cpp:245:5: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation]
  245 |     if(slot >= nslots || slot < 0)
      |     ^~

  248 |         assert(p);

Note: this warning is reported by gcc 11.2.1, on Fedora 35.
