refactor: create enum class for label type

[nsenave]

Summary

• Enum for valid label types #72

The "type" property of label objects was implemented as a String. Yet, only precise values are valid for Lunatic.

➡️ The string property should be replaced with an enum

Goal: apply this change in a transparent way, to do it gradually.

Done

• Methods String getType() and setType(String) are unchanged and marked as @Deprecated
• Create LabelTypeEnum class
• Add methods LabelTypeEnum getTypeEnum() and setType(LabelTypeEnum)
• Getters and setters are made so that the usage of string or enum for this property is as transparent as possible in the java api of the lib
• Serialization and deserialization of this property is transparent for clients (json content is unchanged)

In a later version:

• the string version of this property will be completely removed
• the getType() method will return a LabelTypeEnum value
• the getTypeEnum() method will be marked as @Deprecated

In an even later version:

• the getTypeEnum() method will be removed

(In the end: it will be as if this property has always been an enum)
