11 fbae does not compile with apple clang because of jthread

[simatic]

In addition to using tasks instead of threads, we took car of the following problems/additions :

• Use std::move to process messages going from CommLayer to SessionLayer
• Use std::move in deserializeStruct to reduce memory allocations. For both of these improvements, tests made with valgrind show (valgrind ./fbae -a B -c t -f 100 -n 500 -r 99 -s 1024 -S ../../Resources/sites_3_local.json) show that heap summary
  • goes from `total heap usage: 72,899 allocs, 72,899 frees, 136,927,427 bytes allocated
  • to total heap usage: 60,288 allocs, 60,288 frees, 116,008,901 bytes allocated
• Add CPU time to displayed statistics

Here is an example of displayed statistics (Note how CPU time is ~3 times elapsed time):
