Consider adding support for Symbolic Versioning

[xaocon]

Please describe your feature request. It would be very helpful to have support for Symbolic Versioning (eg. semver). The exact implementation isn't up to me but a minimum being able to do comparisons would be nice. I think that trying to parse all strings and determine if they are semver would result yq doing things that people don't expect so I think either a flag to enable or a new set of functions for dealing with them would be the way to go.

Describe the solution you'd like If we have data1.yml like:

- 0.9.0
- 0.9.1
- 0.10.0

And we run a command:

yq 'map(. | as_symver) | sort_by(.)'

output would be

- 0.9.0
- 0.9.1
- 0.10.0

instead of

- 0.10.0
- 0.9.0
- 0.9.1

Describe alternatives you've considered Maybe a custom tag would be a better alternative?
