Compatibility with EPSG:29882

[danieltulp]

I'm having trouble getting this to work with EPSG:29882.
I keep getting a Colum is out of bounds error from the WMTS service, as it exceeds the max value.
This is because the WMTS service uses the EPSG:29882 projection.
Altering the top left corner to the one the WMTS provides doesn't help.

Seems like this plugin assumes EPSG:3857 matrixes unles one passes it as (undocumented) option... see

leaflet.TileLayer.WMTS/leaflet-tilelayer-wmts-src.js

Line 33 in d5d162d

this.matrixIds = options.matrixIds||this.getDefaultMatrix();
