Testing and issues for new WMTS Probes

Describe the bug

Via issue #379 and PR #406 some new custom WMTS Probes were added. This issue is opened to discuss some problems when testing these Probes with various WMTSs. NB: problems may well be related to the WMTS instances themselves. Sometimes it is hard to assess.

Tested several WMTSs using the WMTS GetTile for all layers. Probe. Direct access to the WMTSs in the GHC Demo site: https://demo.geohealthcheck.org/resources?resource_type=OGC%3AWMTS

Below results and and log output from GHC demo Web app for the various WMTSs.

General Findings

even if the 'All Layers' Probe was chosen, in the Probe UI still individual layers could be chosen
guess sample means that the Probe makes a random choice, like a random Layer/Tile?
Capabilities Probe worked for each WMTS

PDOK BRT

URL https://service.pdok.nl/brt/achtergrondkaart/wmts/v2_0

No problems detected. Tried several variants for both Probes.

IGN Geoportail (French GDI)

Strange errors related to WMTS not returning image formats but looks like Vector Tiles application/x-protobuf. So maybe not an issue. (?)

Strange problem getting Bounding box when adding the Probe. Log output below.
