Lightweight package meant to provide functionality and syntax for [swizzling](https://en.wikipedia.org/wiki/Swizzling_(computer_graphics)) operations.

Swizzling is defined for any linearly indexable object, the main example of which are `AbstractVector`.

```julia

julia> using Swizzles

julia> v = [10, 20, 30, 40];

julia> swizzle(v, 3, 1)

2-element Vector{Int64}:

 30

 10

```

Besides extracting vector components, swizzling may be used for mutation, with `swizzle!`:

```julia

julia> v = [10, 20, 30, 40];

julia> swizzle!(v, [1, 2], 4, 2)

2-element Vector{Int64}:

 1

 2

julia> v

4-element Vector{Int64}:

 10

  2

 30

  1

```

Additionally, a `@swizzle` macro is defined which provides nice syntax for it:

```julia

julia> v = [10, 20, 30, 40];

julia> @swizzle v.xy

2-element Vector{Int64}:

 10

 20

julia> @swizzle v.rgb

3-element Vector{Int64}:

 10

 20

 30

julia> @swizzle v.xyx

3-element Vector{Int64}:

 10

 20

 10

julia> @swizzle v.wx = [1, 2]

2-element Vector{Int64}:

 1

 2

julia> v

4-element Vector{Int64}:

  2

 20

 30

  1

```
