feat(geom): Add support for multi-geometries [OL5]

[samuel-girard]

Hello,

This change brings support for multi-geometries.
The change is to be applied only after #183 is merged.

There is just one breaking change: the coordinates input on CollectionCoordinatesComponent is not anymore limited to type [number, number][], but it supports all types of coordinates.
That means the existing code must be updated for polygons:
Old style:

<aol-feature>
    <aol-geometry-polygon>
        <aol-collection-coordinates
            [coordinates]="[[5, 45],[5.05, 45.05],[5.05, 44.95],[4.95, 44.95]]"
            [srid]="'EPSG:4326'"
        >
        </aol-collection-coordinates>
    </aol-geometry-polygon>
    <aol-style>
        <aol-style-stroke [color]="'red'"></aol-style-stroke>
        <aol-style-fill [color]="[255,0,0,0.5]"></aol-style-fill>
    </aol-style>
</aol-feature>

New style:

<aol-feature>
    <aol-geometry-polygon>
        <aol-collection-coordinates
            [coordinates]="[[[5, 45],[5.05, 45.05],[5.05, 44.95],[4.95, 44.95]]]"
            [srid]="'EPSG:4326'"
        >
        </aol-collection-coordinates>
    </aol-geometry-polygon>
    <aol-style>
        <aol-style-stroke [color]="'red'"></aol-style-stroke>
        <aol-style-fill [color]="[255,0,0,0.5]"></aol-style-fill>
    </aol-style>
</aol-feature>

Notice the [coordinates] input is now a [number, number][][], as defined in GeoJSON.

This also allows to display polygon with holes, which is not possible with the current code.

@samuel-girard I fixed the linting problem on next branch, could you rebase please ?

Hi all,

I rebase this branch on next after merging OL5 PR.
This introduce a breaking change.
It LGTM but I would like to have another review

That seems alright to me. I made some feedback on details.

The only breaking change is to finally use the coordinates entirely and therefore correctly 😄 :

<aol-collection-coordinates [coordinates]="f.geometry.coordinates[0]"></aol-collection-coordinates>	                

become :

<aol-collection-coordinates [coordinates]="f.geometry.coordinates"></aol-collection-coordinates>

@kekel87 agree with changes?

[kekel87]

@Yakoust Yep i agree 👍
