Add Sendable conformance to JMESExpression

• Fix warning from Swift 5.6

• Add JMESPropertyWrapper protocol to aid Mirror parsing of property wrappers

• Renamed Expression to JMESExpression
• Got tests compiling on iOS

Add support for Mirror collection and dictionary display types

Expression.search(Any) -> Expression.search(object: Any)

• Don't convert .other(any) to String
• Removed RawRepresentable versions of Expression.search

• When creating JMESVariable for an object we cannot parse instead of outputting a .null output .other(any).
• When collapsing a JMESVariable.other return a string representation of it via String(describing:)
• Add Expression.search functions that cast to a RawRepresentable via init(rawValue)
• Add more descriptive errors
• Add Expression.search functions that take json in Data format

• Optimisation: Stop processing the whole JSON object to calculate types. Only calculate types for objects we need to parse
• Rename Function -> JMESFunction
