Rust SGX SDK 2.0.0 has implemented sgx_protected_fs with Rust, and can support the use inside and outside the Enclave. I think you can replace protected_fs_rs with sgx_protected_fs in 2.0.0.

Just talked with @volcano0dr. The sgx_tprotected_fs may need time to support ios/mac. We cannot support ios/mac in this PR and will use the support when it is ready in the future.

@mssun I cannot open PR to https://github.com/apache/incubator-teaclave-crates as it is empty. So I pushed the crates to https://github.com/mesatee/crates. The code is tested. You can upload the code directly to incubator-teaclave-crates. Let me know after the upload.

I created a README.md file. You can now submit PR.
