[RFC]: Add `@stdlib/random/strided/randi`

### Description

This RFC proposes adding support for filling a strided array with random integers and with the option to select the underlying PRNG. This is the strided array interface analog of `@stdlib/random/base/randi`.

Package: `@stdlib/random/strided/randi`
Alias: `randi`

### Related Issues

None.

### Questions

No.

### Other

- A package with a similar implementation/API design is [`@stdlib/random/strided/randu`](https://github.com/stdlib-js/stdlib/tree/develop/lib/node_modules/%40stdlib/random/strided/randu).

### Checklist

- [X] I have read and understood the [Code of Conduct](https://github.com/stdlib-js/stdlib/blob/develop/CODE_OF_CONDUCT.md).
- [X] Searched for existing issues and pull requests.
- [X] The issue name begins with `RFC:`.

Start by comparing the proposed package @stdlib/random/strided/randi with @stdlib/random/strided/randu and the analogous @stdlib/random/base/randi implementation. Done means adding the strided random-integer package under the requested alias, supporting selection of the underlying PRNG, and matching the established API and package conventions.
