CodeSystem name is not supported

[elsaperelli]

While addressing this cql-execution Issue, I noticed that the translator doesn't recognize CodeSystem.name, which was introduced in CQL 1.5: https://cql.hl7.org/09-b-cqlreference.html#codesystem.

When I try translating the following CQL, I get the following Error: "Member name not found for type System.CodeSystem".

codesystem "MyCS": "http://example.com" version '1'
define function GetCodeSystemName(cs CodeSystem): cs.name
define MyCSName: GetCodeSystemName(MyCS)

I also tried the following CQL and got the same error:

define CanConstructCS: exists (
    (CodeSystem { id: 'foo', version: '1', name: 'Foo' }) CS
      where CS.id = 'foo' and version = '1' and name = 'Foo'
)
