High performance LTSV (Labeled Tab Separeted Value) parser for Go.
About LTSV: http://ltsv.org/
Labeled Tab-separated Values (LTSV) format is a variant of
Tab-separated Values (TSV). Each record in a LTSV file is represented
as a single line. Each field is separated by TAB and has a label and
a value. The label and the value have been separated by ':'. With
the LTSV format, you can parse each line by spliting with TAB (like
original TSV format) easily, and extend any fields with unique labels
in no particular order.
