[New feature] Add an error management

[jecisc]

I tried to import a TypeScript project to do some benchmarks but it was failing because of a missing property on a node.

Parsing and importing models is something complex and it is easy to have errors but that should not prevent to have a model.

I propose to add an error management is #visitNode: so that we catch potential errors and if we have some, we display them in an error report.

I already have this mechanism in other importers projects but it is in my SymbolResolver project.
I'll fix this issue either by duplicating the code in Pharo-Tree-Sitter, or better, extract this error management in another project that could be used by both Famix-TreeSitter-Integration and Pharo-Tree-Sitter.

Opening an issue to not forget about that.
