A recursive function to map an object keys
import { isPlainObject } from '@salesforce/ts-types';
/**
* Use mapKeys to convert object keys to another format using the specified conversion function.
*
* E.g., to deep convert all object keys to camelCase: mapKeys(myObj, _.camelCase, true)
* to shallow convert object keys to lower case: mapKeys(myObj, _.toLower)
*
* NOTE: This mutates the object passed in for conversion.
