Transform multiple JSON objects into a flattened data frame.

1	flattenj(dat, sep = "@", compact = TRUE)

`dat`	`list`. Loaded result from a JSON file.
`sep`	`character`. A character/string passed to `flattenj_one`. Defaults to @ to avoid the occasional overriding. Not recommended to use some risky characters like . and \. When `compact=FALSE`, it is unnecessary to assign `sep` explicitly, unless @ has been used in the key fields.
`compact`	logical. Whether to generate the compact or completely expanded data frame. Defaults to `TRUE`.

The function flattens multiple JSON objects into a new data frame. The result contains multiple columns. If compact=TRUE, it returns paths, values and index columns, otherwise level1, level2, ..., values and index. The index column stores the id of each JSON object.
