SVG symbols in WFS

Multiple things seem to be going on:

• primary reason for no icons is that the base64 is malformed/not parsed correctly ( at least for our purposes). String should be in line with data url specifications. What we get starts with base64: where it should be data:image/png;base64,

  EDIT: The correct data URI form is: data:image/svg+xml;base64 not png...obviously. Thats what caused the next problem with sizes.

• after that url should be correct but openlayers throws on image size calcualtion not sure why yet. Will dig deeper later

• Apart from that theres a problem with the processing of QML styles in hslayers where some sort of SLD file seems to be always available as a fallback (at least when loading QML from a file in styler panel, loading from layman seem to be ok ...but still an issue to be dealt with)but that prevents QML from being processed.

Some changes in this branch : https://github.com/hslayers/hslayers-ng/tree/style-qml

• Load geojson + QML styles file to the layman. Couldnt make this wrok . Getting stuck on 'NOT-AVAILABLE' status.. From the response under, can we handle this as completed & failed publication?
  Some more context Allow to upload QML file along with a new vector file in Datasources #3457

Could not really debug. Flower is not available on watlas

After trying to uplad the QML style to existing layman layer seemingly successfully I ended up with a layer that returns?
wfs_wms_status: "NOT_AVAILABLE" for /rest/workspaces/filip1/layers/chargers_nostyles

Looking at layer matedata /rest/workspaces/filip1/layers/chargers_nostyles we can see both both WFS and WMS urls. and error in styles - "message": "GeoServer HTTP or connection error"
