New data type in grid layer

[zeng-hello-world]

I'm using grid_map in my project, and I want add pcl::PointXYZI data type in the layer, but grid_map only support for float type. I know this is for other function , such as filter, but if I just want to store other type of data, I have to code a new data structure. So can other data type be supported in the future?

Thank you!
