Move file caching logic to new FileCache service
Also: removes the -re ffmpeg option.
If this option is passed, ffmpeg won't write to fs-capacitor (and the cache file) as fast as possible.
In other words, the cache file won't finish writing until the entire stream has been played.

Muse is a **highly-opinionated midwestern self-hosted** Discord music bot **that doesn't suck**. It's made for small to medium-sized Discord servers/guilds (think about a group the size of you, your friends, and your friend's friends).
### Features
- 🎥 Livestreams
- ⏩ Seeking within a song/video
- 💾 Local caching for better performance
- 📋 No vote-to-skip - this is anarchy, not a democracy
- ↔️ Autoconverts playlists / artists / albums / songs from Spotify
- ↗️ Users can add custom shortcuts (aliases)
- 1⃣ Muse instance supports multiple guilds
- ✍️ Written in TypeScript, easily extendable
- ❤️ Loyal Packers fan
### Design Philosophy
I believe it makes much more sense to let Discord handle user permissions (whenever possible) rather than building them into a bot and adding additional complexity. Instead of only allowing users with a certain role to control Muse, Muse allows anyone who has access to its bound channel to control it. Instead of specifying the owner as a user ID in the config, Muse simply looks at the guild owner.
### Running
Muse is written in TypeScript. You can either run Muse with Docker (recommended) or directly with Node.js. Both methods require API keys passed in as environment variables:
- `DISCORD_TOKEN` can be acquired [here](https://discordapp.com/developers/applications) by creating a 'New Application', then going to 'Bot'.
- `SPOTIFY_CLIENT_ID` and `SPOTIFY_CLIENT_SECRET` can be acquired [here](https://developer.spotify.com/dashboard/applications) with 'Create a Client ID'.
- `YOUTUBE_API_KEY` can be acquired by [creating a new project](https://console.developers.google.com) in Google's Developer Console, enabling the YouTube API, and creating an API key under credentials.
Muse will log a URL when run. Open this URL in a browser to invite Muse to your server. Muse will DM the server owner after it's added with setup instructions.
#### Docker
(Replace empty config strings with correct values.)
```bash
docker run -it -v "$(pwd)/data":/data -e DISCORD_TOKEN='' -e SPOTIFY_CLIENT_ID='' -e SPOTIFY_CLIENT_SECRET='' -e YOUTUBE_API_KEY='' codetheweb/muse
```
This starts Muse and creates a data directory in your current directory.
**Docker Compose**:
```yaml
version: '3.4'
services:
muse:
image: codetheweb/muse
restart: always
volumes:
- ./muse:/data
environment:
- DISCORD_TOKEN=
- YOUTUBE_API_KEY=
- SPOTIFY_CLIENT_ID=
- SPOTIFY_CLIENT_SECRET=
```
#### Node.js
**Prerequisites**: Node.js, ffmpeg
1. `git clone https://github.com/codetheweb/muse.git && cd muse`
2. Copy `.env.example` to `.env` and populate with values
3. `yarn install` (or `npm i`)
4. `yarn build` (or `npm run build`)
5. `yarn start` (or `npm run start`)
**Note**: if you're on Windows, you may need to manually set the ffmpeg path. See [#345](https://github.com/codetheweb/muse/issues/345) for details.
#### Advanced
By default, Muse limits the total cache size to around 2 GB. If you want to change this, set the environment variable `CACHE_LIMIT`. For example, `CACHE_LIMIT=512MB` or `CACHE_LIMIT=10GB`.
