v5.0.0

This release incorporates a handful of changes over the past few months and various proposals from the JSON Logic Organization discussions.

What this release officially introduces

• try / throw
• val / ?? / exists
• Some changes for comparison operators

What this release changes

• traverse: false is now passed in as lazy: true, however, this property should be remapped to avoid user rewrites. This conversation ties to this
• Empty Arrays are falsy by default.
• Empty Objects are falsy by default.
• Any structures (Map, Set) are also seen as falsy.
• all is false when the input is empty.
• The length operator is treated like a unary operator, and should be more consistent.

Most users of this library shouldn't need to rewrite anything, but it might change some assumptions about truthiness / falsiness
