Add logValue Method for Range Inputs to p5.Element

[nimanns]

Changes: This PR introduces a new method, logValue, to the p5.Element prototype for range () elements. This method allows users to map slider values logarithmically, which is particularly useful for applications like audio volume control, where perception of changes follows a logarithmic rather than linear scale.

Changed files are: src/dom/dom.js and test/unit/dom/dom.js

is this based on some issue? I am curious why we add this directly to the element and not create mapping functionality / utillity to the logarithmic domain.
