percent encoding issue with IDs

[denis-yuen]

The current specification is pretty descriptive rather then prescriptive when it comes to ID format.

We have in the main readme

ID: globally unique across systems and also identifies the system that it came from (ex: 123456323@agora.broadinstitute.org )

In #164 we have

To ensure that versioned TRS URIs can be unambiguously parsed by clients, any / characters potentially occurring in tool and tool version identifiers would need to be percent-/URL-encoded before sharing a versioned TRS URI.

This breaks out this issue for discussion. For background, Dockstore uses percent encoded slashes but this can place a burden on implementer of the standard to handle these in a secure way
