Support allowed R5 resources in R4/R4B IGs

To better support emerging IG authoring features, a subset of R5 resources can be used in R4 and R4B IGs. Authors can create instances of these resources, but may not profile them. This feature has been available in the IG Publisher previously and is now available in SUSHI. Authors may now use FSH to define instances of the following R5 resources in R4 and R4B IGs:

• ActorDefinition
• Requirements
• SubscriptionTopic (R4 only; R4B uses the R4B SubscriptionTopic)
• TestPlan

Use title, name, and description values in IG resource list

When SUSHI creates the ImplementationGuide resource for an IG, it generates the resource list based on the items defined in the IG (or supplied in input/*). Since each resource in the list needs a name and description specified, SUSHI determines the appropriate name and description from the resource metadata. Prior to SUSHI 3.4.0, SUSHI only extracted metadata from FSH keyword values; now SUSHI will extract metadata from the title, name, or description resource elements when Title: or Description: keywords are not present.

With this change, authors may notice that their resources have more meaningful or user-friendly names in the IG's generated table of contents. In addition, the ordering of the resources in the table of contents may change since the default sort order is by name.

Update automatic dependencies

SUSHI now loads automatic dependencies in a way that is more consistent with the IG Publisher's approach:

• R4 and R4B IGs auto-load hl7.fhir.uv.tools (current), hl7.terminology.r4 (latest release), and hl7.fhir.uv.extensions.r4 (latest release)
• R5 IGs auto-load hl7.fhir.uv.tools (current), hl7.terminology.r5 (latest release), and hl7.fhir.uv.extensions.r5 (latest release)

New Contributors

• @mrcerf made their first contribution in #1345
