Indicate version support on each tool, library, platform

[Stephen-Gates]

On the tools page it is not clear what version of the specification is supported by each tool.

This causes confusion and frustration. E.g. I have be teaching people about data packages at work, they hand craft a schema and package but when they use the schema/package in various tools they get errors due to varying levels of support.

I suggest a simple icon be added to each tool listing to indicate v1 or pre v1 support.

Or you could get fancy as ask each implementation to document their level of support, see:

• Implementations status software-legacy#26
• Add FD Specification compliance statement qcif/data-curator#394 (comment)
