Parse HH:MM:SS strings into a Go time.Duration type.
Install this package with:
go get github.com/dannav/hhmmss
Given the following string 03:30:26 call the package's Parse method:
dur, err := hhmmss.Parse("03:30:26")
Parse returns a time.Duration value that allows you to retrieve the value's time
in seconds, hours, minutes, etc.
If an integer string is passed to Parse the argument will be treated as seconds.
