f6bea9f048 feat: experimental support for other file types
chore: migrate to rodio v0.21.1
feat: add a currently nonfunctional source argument to the scrape
command

well, this is an important commit for anyone who has some interest in
the workings of lowfi, so strap in.

rodio finally updated cpal, so that ugly unsafe bit of code to implement
send is no longer necessary since cpal did it themselves (a year ago)
they also removed output stream handles and some other things which
nobody really used anyway.

next, the other file types is literally not even code, just adding a
feature flag which enables the default rodio feature flags. i do feel a
bit silly for thinking it'd be super difficult, so thanks rodio.

lastly, the source flag is for a possible switch to the chillhop
tracklist. anything embedded into lowfi should be generated with an open
source script, hence if lowfi does switch to chillhop, it'll need to be
selectable.

# Using the chillhop list
## Linux

```
## Windows
Go to `%appdata%` in Explorer, then `Roaming`, and make a folder called `lowfi`.
Then just put [this file](https://raw.githubusercontent.com/talwat/lowfi/refs/heads/main/data/chillhop.txt) in there.
## Launching lowfi
Once the list has been added, just launch `lowfi` with `-t chillhop`.

# Environment Variables
Lowfi has some more specific options, usually as a result of minor feature requests, which are only documented here.
If you have some behaviour you'd like to change, which is quite specific, then see if one of these options suits you.
* `LOWFI_FIXED_MPRIS_NAME` - Limits the number of lowfi instances to one, but ensures the player name is always `lowfi`.
* `LOWFI_DISABLE_UI` - Disables the UI.

### Extra Flags
If you have something you'd like to tweak about lowfi, you can run `lowfi help`
to view the available options.
If you have something you'd like to tweak about lowfi, you use additional flags which
slightly tweak the UI or behaviour of the menu. The flags can be viewed with `lowfi help`.
| Flag | Function |
| ----------------------------------- | ---------------------------------------------- |
| `-a`, `--alternate` | Use an alternate terminal screen |
| `-m`, `--minimalist` | Hide the bottom control bar |
| `-b`, `--borderless` | Exclude borders in UI |
| `-p`, `--paused` | Start lowfi paused |
| `-d`, `--debug` | Include ALSA & other logs |
| `-w`, `--width <WIDTH>` | Width of the player, from 0 to 32 [default: 3] |
| `-t`, `--track-list <TRACK_LIST>` | Use a [custom track list](#custom-track-lists) |
| `-s`, `--buffer-size <BUFFER_SIZE>` | Internal song buffer size [default: 5] |

lowfi won't put a `/` between the base & track for added flexibility, so for most cases you
should have a trailing `/` in your base url. The exception to this is if the track name begins
with something like `https://`, where in that case the base will not be prepended to it.

lowfi would download these three URLs:
- `https://lofigirl.com/wp-content/uploads/2023/06/Foudroie-Finding-The-Edge-V2.mp3`
- `https://file-examples.com/storage/fea570b16e6703ef79e65b4/2017/11/file_example_MP3_5MG.mp3`
- `https://file-examples.com/storage/fe85f7a43b689349d9c8f18/2017/11/file_example_MP3_1MG.mp3`
- `https://lofigirl.com/wp-content/uploads/2023/04/2-In-Front-Of-Me.mp3`
Additionally, you may also specify a custom display name for the track which is indicated by a `!`.
For example, if you had an entry like this:
```txt
2023/04/2-In-Front-Of-Me.mp3!custom name
```
Then lowfi would download from the first section, and display the second as the track name.
You can also prepend `file://` to the header track name, which will make lowfi treat it as a local file.
This is useful if you want to use a local file as the base URL, such as:
```txt
file:///home/user/Music/
file.mp3
file:///home/user/Music/second-file.mp3
```
Further examples can be found in the [data](https://github.com/talwat/lowfi/tree/main/data) folder.
