Parse quoted values as strings

[yonaskolb]

Is it possible to configure Yams to parse a quoted value (single or double quotes) as a string, instead of trying to convert to an assumed Swift type?

version: "10.10" // want it to parse to "10.10" String instead of 10.1 Float

I know it's possible to use an explicit type tag as a workaround, but it would be nice to be able to just quote a value which I thought is the standard way of specifying strings in yaml.

version: !!str '10.10' // correctly parses as "10.10"

This would fix yonaskolb/XcodeGen#268

Currently there is no API to change the parsing result with or without quotation marks.
It is advisable to handle types correctly by using Codable, so I tried to implement using YAMLDecoder on XcodeGen.
Since some of XcodeGen's implementation depends on [String: Any], some types can not successfully implement as Decodable. 🤔
e.g. https://github.com/norio-nomura/XcodeGen/blob/use-yaml-decoder/Sources/ProjectSpec/Settings.swift#L79-L94

As I confirmed the behavior of PyYAML, it seems to be a bug that Yams guesses the type ignoring quotes.
I will change this behavior.

Fantastic, thank you @norio-nomura! 😄
