indy-shared-rs dependencies issues in vdr version 0.3.1 & 0.3.0

[gmulhearn-anonyome]

Running a cargo check on a project with an indy-vdr 0.3.1 or 0.3.0 dependency will fail to compile due to mismatching types. This has to do with the different versions of indy-data-types and indy-utils that indy-vdr depends on, which under certain circumstances can cause indy-vdr to be consuming two different versions of indy-utils.

e.g. a cargo tree under a project with a single dependency on indy-vdr = "=0.3.0":

└── indy-vdr v0.3.0
    ├── indy-data-types v0.5.1
    │   ├── indy-utils v0.5.0
    │   │   ├── indy-wql v0.4.0
    ├── indy-utils v0.4.0

this causes errors such as the following:

I'm unsure of the best solution to this issue, in general, the cross-dependencies happening in indy-shared-rs seem risky imo

Possibly related to #78 due to similar errors. However, vdr 0.3.4 seems fine.
