// Maximum length of the metadata associated with an object.
// Setting to non-zero value enables metadata-related API but also
// changes the on-disk format, so the change is not backward-compatible.
//
// Do note: the meta length must never exceed
// logical_page_size - (SPIFFS_OBJ_NAME_LEN + 64)
//
// This is derived from following:
// logical_page_size - (SPIFFS_OBJ_NAME_LEN + sizeof(spiffs_page_header) +
// spiffs_object_ix_header fields + at least some LUT entries)
