Credible bug: [BUG] Unable to build DIDKit due to multiple definitions of sha256 and generate_ed25519

[Mikerah]

Describe the bug
When building DIDKit according to the instructions found here, I encountered to errors relating to duplication of definitions of sha256 and generate_ed25519. These definitions are actually found in the ssi crate and is causing the building process to fail.

These are the outputs:

error[E0428]: the name `sha256` is defined multiple times
  --> /home/mikerah/Documents/Projects/ssi/src/hash.rs:13:1
   |

   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ `sha256` redefined here

   = note: `sha256` must be defined only once in the value namespace of this module

Thanks for opening an issue @Mikerah, please try the instructions here to exclude the WASM package for now: https://github.com/spruceid/didkit#manual

Specifically, with our introduction of WASM, there were competing features for ssi. We believe that packaging for crates.io and adding some more sophistication in our build process will resolve this.

We have tracked this issue more broadly here to ensure it doesn't re-occur: #63

Hi @Mikerah, with #65 I believe this should be resolved. Could you please confirm? Thanks.

I can confirm that with #65, I was able to build didkit.
