Lists/arrays

```
MOVES EQU [$24, $3a]

db LENGTH(MOVES)
db MOVES[0], MOVES[1]
```

Is there any chance for something like this to happen at all? Is it even a good idea?

Should be made to work for strings too.

```
POKEMON_NAMES EQU ["BULBASAUR", "IVYSAUR"]

db "So you want ", POKEMON_NAMES[STARTER1], "?@"
```

Start by reviewing how the assembler currently represents constants and handles indexing, then compare the requested numeric and string examples against existing syntax and tests. Done means reaching a documented decision on whether lists and indexed string lists are supported, with behavior and tests covering the proposed forms.
