Incorrect parsing of Double values if the fraction part starts with zeroes

[vzsg]

Consider the following JSON with three double values: [0.608, 0.0608, 0.00608]. When parsed with Jay, the resulting array contains 0.608 three times, so the scale is completely lost.

In other words:

import Jay

let testData = Array("[0.608, 0.0608, 0.00608]".utf8)

let jay = Jay()
let json = try jay.anyJsonFromData(testData)
print(json) // [0.60799999999999998, 0.60799999999999998, 0.60799999999999998]

After some investigation, the culprit is NumberParser.swift:202, where the collected fractional digits are naively converted to an integer. For example when parsing the third number, the digs array ["0", "0", "6", "0", "8"] becomes 608, losing the two initial zeroes.
