MaxWeightExceptParser doesn't suppport `maxweightrating:conditional` and others

**Describe the bug**

We currently support the conditional variant of the `maxweight` tag as well as the more broad tagging schema `{ACCESS}:conditional`

Missing variants:

* `maxweight:{ACCESS}:conditional` like `maxweight:hgv:conditional` [Taginfo](https://taginfo.openstreetmap.org/keys/maxweightrating%3Ahgv%3Aconditional)
* `maxweightrating:conditional` [Taginfo](https://taginfo.openstreetmap.org/keys/maxweightrating%3Aconditional)
* `maxweightrating:{ACCESS}:conditional` [Taginfo](https://taginfo.openstreetmap.org/keys/maxweight%3Ahgv%3Aconditional)

**To Reproduce**

Steps to reproduce the behavior. For examples:

1. checkout recent and stable version of GraphHopper
2. link to your OSM pbf
3. include the config.yml you are using
4. run `java -Ddw.graphhopper.datareader.file=your.osm.pbf -jar *.jar server config-example.yml`

Instead of a manual reproduction it would be even better to have a unit or integration test reproducing the issue.

**Expected behavior**

The MaxWeightExceptParser should handle the conditional variants of the tags the OSMMaxWeightParser supports.

Start by locating MaxWeightExceptParser and OSMMaxWeightParser, then compare how each recognizes conditional tags. Add coverage for the three listed tag variants and verify that MaxWeightExceptParser handles them consistently with the tags supported by OSMMaxWeightParser.
