These are pretty simple and just to kick things off. We can always put in a conversion library
going forward.

The conversions are part of a larger strategy for supporting natural language queries. So
I just wanted something to get started with.

> Based on the work in SOLR-10485 I think it makes sense to add Conversion evaluators.
I think a good place to start is with the conversions listed here:
> https://www.learner.org/interactives/metric/conversion_chart.html#1
> This ticket will add length conversions and lay down the initial syntax.
> Sample syntax:
> {code}
> select(eval(), convert(inches, meters, 22) as meters)
> {code}
> This will return a single tuple with 22 inches converted to meters.
