Summary

This pull request resolves a stdlib/no-new-array ESLint error in the format_data.js utility within the @stdlib/plot/unicode/stemleaf package. The change updates the array initialization and population method to comply with project coding standards.

Root Cause

The code used new Array(number) to pre-allocate an array, which is disallowed by the stdlib/no-new-array lint rule. This rule is in place to prevent common bugs associated with the Array constructor and to promote a consistent coding style using array literals ([]).

Changes

• Replaced out = new Array(data.length) with an empty array literal initialization out = [].
• Changed the method for adding elements to the array from index assignment (out[i] = ...) to out.push(...).

Risk & Rollback

• Risk: Low. This is a non-functional change that only addresses code style. The modified behavior (producing a dense array instead of a sparse one) is more correct for the intended use case.
• Rollback: The commit can be safely reverted using git revert <commit_hash> if any issues are discovered.
• Read, understood, and followed the contributing guidelines
