* Non-int versions of `Point` and `Displacement`
This will allow us to make some structs, such as `ActorPosition`, much
smaller.
* ActorPosition: Use smaller types
`Monsters`: 56K -> 46K
* player.cpp: Reduce size of `DirectionSettings`
* CrawlTable: Displacement -> DisplacementOf<int8_t>
* CrawlTable: vector<vector> -> array<vector>
Also only allocate one vector during construction instead of two.
A bit less indirection.
* Monster#enemyPosition: Point -> WorldTilePosition
sizeof(Monster): 240 -> 232
* Monster: Further optimize field layout and sizes
sizeof(Monster): 232 -> 208
`Monsters` is down to 40,000 bytes
* DMonsterStr: _mx/_my -> position
The monster id naming convention was inconsistent with several names being used: i, mid, mon, mi, monsterId
This chanage normalises all names to monsterId
Reduces the size of the `PathNodes` array from 28 KiB to just 8 KiB.
Also reduces the size of `pnode_tblptr` from `300 * sizeof(void *)` to
`300 * 2` bytes.
1. Do not modify the map after loading. Instead, return string views
(guaranteed to be null-terminated) from look up functions and return
the key directly if not found.
2. Use an `unorded_map` instead of `map` where available (C++20).
Saves a bit of RAM (~50 KiB) and improves lookup performance.
Introduces new functions to check for presence of and remove player items.
These functions do not rely on or expose item indices.
They're implemented as free functions instead of Player methods due to
complicated include dependencies between `player.h`, `inv.h`, and
`inv_iterators.h`. We should probably look into cleaning this up at some
point.
