The node of a disembark-action can no longer be part of a hero-chain since sea-to-land-trade isn't possible and landing first eats up all movement-points.
`onetbb/2021.10.0` adds a transitive dependency for `hwloc/2.9.1`
The problem is that `hwloc` does not support mobile OS.
```
checking which OS support to include... Unsupported! (aarch64-apple-ios)

...which eventually leads to:

- This is more clear - in case if building generates queries
- Avoids some edge cases, like what to do if building is single-use and
town has 2 heroes
- In line with hota version of this feature
Manarecoveryreward now uses float instead of unsigned int in order to avoid extremely high instead of negative scores when the hero has more mana than his mana-limit for example due to mana-vortex.
Moved upgrading armies to a lower priority tier as otherwise the AI would go back to their cities all the time even though there were plenty of other things to do.
Improved exploration logic by putting different kinds of exploration to different priority-tiers.
Looking at the other side of a portal has high priority, visiting an observatory has medium priority and scouting by visiting nearby tiles has low priority.
