Add question type : related to map

[CorentinLemaitre]

Hello,

I have seen news about form. It is really great to have powerfull private form. Thanks for that. I have a proposal of a new question type : question related to a map. It could be a point to locate or even a line or a surface, it could be also multiple point or multiple line. There is other nextcloud project that are realted to map that may make it easier to develop. There is also the OpenDataKit project that use this kind of question for code inspiration.
