A library for dealing efficiently with Dynamic non-interleaved audio
buffers.

The buffer is constructed similarly to a `Vec<Vec<T>>`, except the interior
vector has a fixed size. And the buffer makes no attempt to clear data which
is freed when using functions such as [Dynamic::resize].

```rust
use rand::Rng as _;

let mut buffer = rotary::Dynamic::<f32>::new();

buffer.resize_channels(2);
buffer.resize(2048);

/// Fill both channels with random noise.
let mut rng = rand::thread_rng();
rng.fill(&mut buffer[0]);
rng.fill(&mut buffer[1]);
```

You can use masked audio buffers if you need the ability to temporarily
enable or disable channels. This requires that you specify the type of the
mask. A good option for this is a [BitSet<u128>], which supports up to 128
channels.

```rust
use rotary::BitSet;

let mut buffer = rotary::MaskedDynamic::<f32, BitSet<u128>>::with_topology(4, 128);

buffer.mask(1);

for  channel in buffer.iter_mut() {
    for b in channel {
        *b = 1.0;
    }
}

let expected = vec![1.0f32; 128];

assert_eq!(&buffer[0], &expected[..]);
assert_eq!(&buffer[1], &[][..]);
assert_eq!(&buffer[2], &expected[..]);
assert_eq!(&buffer[3], &expected[..]);
```

For convenience we also provide the [dynamic!] macro when constructing
audio buffers.

```rust
use rotary::BitSet;

let mut buf = rotary::Dynamic::<f32>::with_topology(4, 128);

for channel in &mut buf {
    for f in channel {
        *f = 2.0;
    }
}

assert_eq!(buf, rotary::dynamic![[2.0; 128]; 4])
```
