[FEATURE]: Method to convert all fields to camelCase when using db.execute

Problem

Describe what you want EDIT: The casing can be fetched from the global config, as described in #2834, instead of having some arbitrary method for it. When using `db.execute`, the fields remain the same case as they are in the DB; this is totally valid and acceptable. However, it would be neat to have a method on it (`$toCamelCase`) that converts all the fields to camelCase. For example, running this method: [code block] currently outputs `{ foo_bar: 'some-value' }`, but with something like `$toCamelCase`, [code block] it would output `{ fooBar: 'some-value' }`. Currently I do this manually; I wonder if the team would consider this since it's kind of subjective. Feel free to close if this is not planned.
