Fetches a GetCapabilities document to enumerate available coverages, then issues a single GetCoverage request per canvas viewport (matching the WMSLayer single-image pattern). Responses are decoded with GDAL via an in-memory virtual filesystem (VSIMemFileFromBuffer) to avoid temporary file I/O.

Version negotiation: the layer first requests WCS 2.0.1. If the server returns an OGC ExceptionReport it retries with 1.1.2, then 1.0.0.
