Keep only one JSON dependency

See original GitHub issue

Currently we depend on 3 JSON libraries 😖 :

GSON which is the historic one (~it should remain only in our demos~, currently it is only used in demos)
minimal-json which replaced it because of simple API. (but it was not replace in demo because of lack of time)
jackson which is the last choice mainly because it supports BigInteger which is needed to support unsigned integer from LWM2M v1.1 but also because minimal-json is not so much active. (e.g.https://github.com/ralfstx/minimal-json/issues/88). We have also some hint which could make us thought that Jackson could be faster. The main drawback of jackson the lib is fat (~1,8 Mo vs ~33 ko) but I guess we will live with it. (except if someone propose a better solution 🤯)

So there is a lot of Serializer/Deserializer to rewrite with Jackson to be able to remove GSON and minimal-json dependencies
