file size inssanity.kt

//saw this insanity from jvm + windows when easton was testing:
// somePath.isReadableFile && Files.size(somePath) < X
// threw an exception, because the file was readable, but its metadata was not readable.
// so Files.size threw. Rediculous. Files suck.
// see the first exception in #2554: https://github.com/EmpowerOperations/OASIS/issues/2554#issuecomment-543897459
