Parse lab values that include a range

[jean-the-coder]

Description

Right now lab values that have a < are parsed as 0. This PR adds some quick parsing so that these are displayed like reference ranges are.

Fixes #441

Changes

• Update observation model to check for ranged values in valueString and the comparator attribute in valueQuantity and return a ValueObject
• Update bar chart to use new ValueObject for values instead of value_quantity_value
  • Normally I would fully remove this value, but I am leaving it for now because it is used in places that I'll be updating soon as part of my changes to address Observations with string/boolean Values display as blank in Charts and fhir-card #360.
• Add valueQuantity trait to observation factory to allow custom values
• Added an observation bar chart story to test display of a ranged value
  • Note: The tooltip is a little wonky with the text display and the color of the result is a little off if there is also a range, but I figure for now this is fine as at least the result is readable without having to dig into the debug json

🤦 - good catch

lol, hey, that 🤦is mine. I'm the one who made this file 😆

I just find it interesting that it all worked regardless. I only noticed it because I was doing some testing in my other branch that has a lot more change going on and storybook finally complained near the end of my changes.

haha, don't be too hard on yourself, I've definitely done stuff like that -- I thought you copy pasted this from my original file :D
