* Deep merges two records by combining their properties.

* The mergeRecords function creates a copy of record1 in a new object called merged
* and iterates over each key in record2. If both values of the corresponding keys
* in record1 and record2 are objects, it recursively calls mergeRecords. If not,
* it assigns the value from record2 to merged. Finally, it returns the merged record.
*
* A third customMerge function arg allows for custom merging of certain values.
*
* @param record1 - The first record to merge.
* @param record2 - The second record to merge.
* @param customMerge - A function allowing custom value merging in certain circumstances.
* @returns The merged record.
