expose functionality of ArxMap.finalize() as cli commands

[meszaros-lajos-gyorgy]

Converting mapdata from ftl to json and back can be done with arx-convert, but that repo doesn't do any checks or validations whether the provided mapdata is actually correct and will it load in the game. Creating a level with arx-level-generator is something like this:

import { ArxMap } from 'arx-level-generator'

const settings = new Settings()
const level = new ArxMap();

// ...

level.finalize(settings) // <----- this part does the "magic"!
level.saveToDisk(settings)

ArxMap.finalize(settings) removes out of bound polygons, calculates normals, room data and lighting. This needs to be exposed, like so:

arx-level-generator finalize level8.fts.json --output=level8.fts.finalized.json

There is one problem: changing the polygons would also affect the llf file, so the cli command would need to have 2 json files as an input and 2 files for output.

ArxMap.finalize() now requires a settings parameter from which 2 parameters are read:

• calculateLighting
• lightingCalculatorMode

Those will have to be passed as cli args as well.

This is still to be finished by implementing the remaining things in src/bin/cli.ts
