Construct storage data in the executor

Constructing storage data can be expensive for large files and can block the event
loop. While ideally we optimize the construction of the data, there are some places
we cannot make it any faster. To avoid blocking the loop, the construction of
the data is now done in the executor by running the data_func in the executor.

There is some risk that the data_func is not thread-safe and needs to be run in
the event loop, but I could not find any cases in our existing code where it
would be a problem
