I am working with typescript and facing an issue by trying to use the following property and methods:

• JSONPath.cache
• JSONPath.toPathArray()
• JSONPath.toPathString()
• JSONPath.toPointer()

When accessing those property or methods I am getting the following errors:
Property 'toPathArray' does not exist on type 'JSONPathType'.ts(2339)

My guess is that the typescript declaration file jsonpath.d.ts is not correct.
