Is it possible to add title and description for algorithm?

@vincentsarago
I can add any parameters and metadata (under inputs_ and outputs_), but current titiler algorithm cannot have title and description. These properties can be very useful for users because most of users don't know what is terrarium, terrainrgb, or custom algorithm.

It would be nice if title and description properties can be included optionally in algorithm details. Is it possible to have them in the response?

For example, response can be as below JSON.

{
  "title": "Hillshade",
  "description": "Hillshade layer description",
   "inputs":{
      "nbands":1
   },
   "outputs":{
      "nbands":1,
      "dtype":"uint8",
      "min":null,
      "max":null
   },
   "parameters":{
      "azimuth":{
         "default":90,
         "title":"Azimuth",
         "type":"integer"
      },
      "angle_altitude":{
         "default":90,
         "title":"Angle Altitude",
         "type":"number"
      },
      "buffer":{
         "default":3,
         "title":"Buffer",
         "type":"integer"
      }
   }
}
