⏪️ Restore factory functions of Zero and EmailAddress to v4.5.1

[LVMVRQUXL]

📝 Description

We want to restore factory functions introduced for the Zero and the EmailAddress types in the version 4.5.1, instead of those introduced for the version 4.5.2, for taking more time to think about the right way for creating instances of a type.

class Zero constructor() {
    companion object {
        fun fromByte(number: Byte): Zero = TODO()
        fun fromByteOrNull(number: Byte): Zero? = TODO()
    }
}

class EmailAddress {
    companion object {
        fun fromString(value: Any): EmailAddress = TODO()
        fun fromString(value: Any, pattern: Any): EmailAddress = TODO()
        fun fromStringOrNull(value: Any): EmailAddress? = TODO()
        fun fromStringOrNull(value: Any, pattern: Any): EmailAddress? = TODO()
    }
}
