Provide source location information with morphir-elm make

[DamianReeves]

Is your feature request related to a problem? Please describe.
In morphir-scala and morphir-dotnet we want to create "analyzers" which allow us to emit warnings/errors as a result of rule/validation violations when we traverse the IR. We would like source location information so that this tooling can appropriately report on the source locations where these analysis errors/warnings occur.

Describe the solution you'd like
Add source location information either directly to morphir-ir.json or as a sidecar JSON file with source location information.

Describe alternatives you've considered
