Feat/remove opinionated storage

[ieow]

== Breaking ==
Tkey should not be opinionated on how the device share is being stored.
remove the storeDeviceShare, the deviceShare can be coded outside tkey.

Example webstorage code implementation

      const tb2 = new ThresholdKey({ serviceProvider: customSP, storageLayer: customSL, manualSync: mode });
      const keyDetails = await tb2.initialize();


      // store device share
      const webStorage = new WebStorageModule();
      webStorage.setModuleReference(tb2)
      
      // if new user, deviceShare should be present
      if (keyDetails.deviceShare) {
          await webStorage.storeDeviceShare(keyDetails.deviceShare, keyDetails.deviceShare.polynomialID)
      } else {
      // not new user, try get deviceShare from web storage
          await webStorage.inputShareFromWebStorage();
      }

     tb2.reconstruct();

I think passing the tkey instance in to the webStorage function would make more clear and prevent mistake.
But the webstorage API will need to change (refactor).

example

      const tb2 = new ThresholdKey({ serviceProvider: customSP, storageLayer: customSL, manualSync: mode });
      const keyDetails = await tb2.initialize();


      // store device share
      const webStorage = new WebStorageModule();
      
      // if new user, deviceShare should be present
      if (keyDetails.deviceShare) {
          await webStorage.storeDeviceShare( tb2,  keyDetails.deviceShare, keyDetails.deviceShare.polynomialID)
      } else {
      // not new user, try get deviceShare from web storage
          await webStorage.inputShareFromWebStorage(tb2);
      }

     tb2.reconstruct();
