[RFC]: add `ndarray/base/scalar-dtype`

[Aniket-SS]

Description

This RFC proposes to add ndarray/base/scalar-dtype that encapsulates the logic for resolving a default ndarray data type from a scalar value.

The scalar-to-dtype resolution logic is currently duplicated across multiple packages (e.g., ndarray/base/atleastnd, ndarray/from-scalar) and should be extracted into a dedicated reusable package.

Related Issues

• TODO comment in ndarray/base/atleastnd/lib/main.js

// For scalar values, resolve a corresponding ndarray data type...
if ( isNumber( v ) ) { // TODO: consider abstracting this logic to an `ndarray/base/scalar-dtype` (???) package, as this logic is found elsewhere (e.g., `ndarray/from-scalar`) and it would be good to avoid duplication, especially as we add support for more ndarray data types
