Proof of concept functions for (mutably) accessing a slice at multiple positions at once via an array of indices.

Provided APIs

This crate implements multiple APIs:

• "simple": accepts a sorted array [usize; N] of indices.
• "simple_result": accepts a sorted array [usize; N] of indices, but with an Result based API.
• "slice_index": accepts a sorted array [I; N] of indices, where I: SliceIndex<[T]>.
• "generic": uses a generic I: Indices<N> that allows for more flexibility.

Example

```rust use indexmany::generic::indexmany_mut;

let mut v = vec![1, 2, 3, 4, 5]; let [a, b, c] = indexmanymut(&mut v, [0, 2, 4]); *a += 10; *b += 100; *c += 1000; assert_eq!(v, vec![11, 2, 103, 4, 1005]); ```

Generated Assembly

The docs contain example functions with their x86_64 assembly codegen. See the [crate::_doc_assembly] module.
