Extract compliance tool to be its own package

We extract the compliance_tool into its own
package, since the functionality is not needed
in the general SDK anymore.

The new aas-compliance-tool can be found
[here](https://github.com/rwth-iat/aas-compliance-tool).

-* check if a given xml, json or aasx file is readable even if it is not compliant to the offical schema
-* check if the data in a given xml, json or aasx file is the same as the example data
-* check if two given xml, json or aasx files contain the same Asset Administration Shell elements in any order
