Parse the given header
string where size
is the maximum size of the resource.
An array of ranges will be returned or negative numbers indicating an error parsing.

signals an unsatisfiable range// parse header from request
var range = parseRange(size, req.headers.range)
// the type of the range
if (range.type === 'bytes') {
// the ranges
range.forEach(function (r) {
// do something with r.start and r.end
})
}
These properties are accepted in the options object.
