Function files.readBytes throw exception IndexOutOfBoundsException

[ortogo]

If i'm set needed count of bytes (argument length) an error occurs:

null in main
        at "readBytes": com.annimon.ownlang.modules.files.files$p@5ecddf8f

java.lang.IndexOutOfBoundsException

When argument offset setted 0, function work normally

Sample code when an error occurred:

f1 = fopen("file.bin", "rb")
array = newarray(10)
readedCount = readBytes(f1, array, 20, 4)
