Fix get function in data_store.py

[wanglec]

Is your feature request related to a problem? Please describe.
The current implementation of the get function has three problems.

• First, it does not generate annotation-like entries with correct begin/end order, will address in Let get function take range annotation #769
• Second, it does not have a defined order for non-annotation-like types.
• Third, it does not cache the find subtype function.

Depends on

• List issues that this one depends on.

Describe the solution you'd like
We may use the co_iterator_annotation_like function to solve the first problem.
To solve the second problem, we may sort all subtypes and subsequently generate entries belonging to each subtype.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context

• This is part of the data efficiency project
• This PR should be made to the master branch.
• After the data tuple class is finished, we may switch to a new branch for integration.
