fix: getData function should only change when getOptions changes

[mcnulty-fp]

Updates the useVisitorData hook to only return a new getData
function when the getOptions parameter is semantically different.
Previously, the getData function would be recreated if the
getOptions parameter was a different object instance but otherwise
equivalent to the last invocation.

The fix stores the getOptions parameter as a property of the state to
ensure that the value used as a dependency in the getCallback call
only changes when the semantics of the options for the get call
change. The state is updated using a pattern to update the state of
a component during a render by guarding that state update with a
conditional. More information about this pattern can be found in the
React docs:

https://react.dev/reference/react/useState#storing-information-from-previous-renders

The usePrevious utility was no longer used so it was removed.

A new unit test is also added that validates the expected behavior of
the getData function returned by useVisitorData.

Fixes #132
Fixes INTER-1277
