Improve memory stored data sharing between cores

[Zapiano]

When we run scenarios using multiple cores, a copy of a Domain instance is passed to each core. Some of the arrays stored in memory and "saved" in a Domain instance scale with the number of locations (e.g. cyclone mortality, DHW and waves). When the number of locations is too high, the impact in running time is massive.

One idea is to use SharedArrays (https://docs.julialang.org/en/v1/stdlib/SharedArrays/). We are open to other proposals.
