add patch wildcard for ig dependencies

[oliveregger]

The NPM fhir specification says:

When packages point to dependencies they should refer to the whole package version number and not use wildcards, except for the patch version in a semver version reference:

"hl7.fhir.core" : "3.0.x"
This x here means that it should a package resolver should accept the package with the highest found patch number.

This PR adds supports for the following use cases:

• if an ig dependency is defined as .x the latest patch version will used from the file package cache or installed from the package server
• if the ValidationEngine is called and a patched version is already specified before the dependency, the patched version will be used.

e.g.:
ch-core is depending on ch-epr-term 2.0.x, see ig

java -jar org.hl7.fhir.validator_cli.jar -version 4.0.1 -ig ch.fhir.ig.ch-core#current HPWengerRole.xml 

will download ch-epr-term 2.0.4 (latest published version) into the package cache and will be used for validation

java -jar org.hl7.fhir.validator_cli.jar -version 4.0.1 -ig ch.fhir.ig.ch-epr-term#2.0.3 -ig ch.fhir.ig.ch-core#current HPWengerRole.xml 

will download ch-epr-term 2.0.3 into the package cache and will be used for validation, ch-epr-term 2.0.4 will not be used

java -jar org.hl7.fhir.validator_cli.jar -version 4.0.1 -ig ch.fhir.ig.ch-epr-term#2.0.4 -ig ch.fhir.ig.ch-core#current HPWengerRole.xml 
java -jar org.hl7.fhir.validator_cli.jar -version 4.0.1 -ig ch.fhir.ig.ch-core#current HPWengerRole.xml 

ch-epr-term 2.0.4 will be used for validation

This PR is depending on a PR for the IG Publisher to support building implementation guide, will follow after this one, since the IG Publisher is depending on this project.

An additional PR for the IG Publisher is not necessary, as soon as the dependency to this project is added it works.
