More examples / documentation on Photon Filesystem

Hi,
Besides the example on how to init, open and write to a iFile in /tree/main/examples/simple, will there be more examples/documentation provided Photon filesystem? With info on the type of settings (for tuning), read/write APIs
I am hoping to test writing and reading sequential files using Photon with io_uring IO Direct, and see how much performance benefit it provides over standard linux fio.

Start with the existing example in examples/simple and inspect the Photon filesystem APIs and settings relevant to initialization, reading, writing, and io_uring direct I/O. Done means adding the requested examples or documentation so users can understand tuning options and sequential read/write usage, with any applicable tests or examples run.
