fix rows_from_file() crash on empty or whitespace-only input

Browse source 
When no format is specified, the auto-detect path calls csv.Sniffer().sniff()
on the first bytes of the file. For empty or whitespace-only files, strip()
produces an empty byte string, causing sniff("") to raise csv.Error.

Return an empty iterator early when first_bytes is empty.
