// FieldsV1 stores a set of fields in a data structure like a Trie, in JSON format.
//
// Each key is either a '.' representing the field itself, and will always map to an empty set,
// or a string representing a sub-field or item. The string will follow one of these four formats:
// 'f:<name>', where <name> is the name of a field in a struct, or key in a map
