[PROJ] Canada Lambert Conformal Conic Projection

[James Banting]

Hi All,

I'm creating a STAC catalog for Canada's SPOT4/5 orthoimagery <https://open.canada.ca/data/en/dataset/d799c202-603d-4e5c-b1eb-d058803f80f9> and I’d like to build a proj json file and include it in the STAC items. 
The proj json schema files seem to indicate that I need an `id` object with `authority` and `code` to be compliant. Since the projection (Canada Lambert Conformal Conic [CSRS]), doesn’t have an EPSG code, I used this:
    "id": {
      "authority": "CANLAMB-CSRS",
      "code": 1
    }

Is this acceptable in proj world? It’s been a while since I’ve had to touch projection files.

As a reference, this is the documentation for the CANLAMB projection <http://ftp.geogratis.gc.ca/pub/nrcan_rncan/image/spot/geobase_orthoimages/doc/GeoBase_spot_en_Orthoimage_Specifications.pdf> (pg 9 of the document, 15 of the pdf) and I’ve attached my take at the proj json file.

Thanks,
