skipBytes attribute

[fomcl]

Sometimes data files contain extra bytes that need to be ignored. For example, files sometimes start with a 3-byte Byte-Order-Mark (BOM) that needs to be removed first. A skipBytes attribute at the data resource level could be used for this. Thus, skipBytes=3 means "skip the first 3 bytes of this particular resource". Negative numbers could be used to skip trailing bytes.
