Runtime crashes with NonEmptyString

[iDmitriyy]

There is a hole allowing to initialize invalid NonEmptyString

let empty1: NonEmptyString = "" // crash 💥

let empty2 = NonEmptyString("") // crash 💥

let empty3: NonEmptyString = "\("")" // crash 💥

The problem seems to be with these conditional conformances:

extension NonEmpty: ExpressibleByStringLiteral where Collection: ExpressibleByStringLiteral

extension NonEmpty: ExpressibleByStringInterpolation where Collection: ExpressibleByStringInterpolation, Collection.StringLiteralType == DefaultStringInterpolation.StringLiteralType

The best approach I see for now is to remove these conformances and replace them with macro #NonEmptyString, which check at compile time.

Any ideas or plans about it?
