PR: Ignore Directory Indexes

[unicornware]

Description

• Updated Trextel to ignore directory index specifiers (i.e: './types', where ./types/index.* is being imported)
• Added Trextel.transform to consolidate transformation logic
• Added TrextNodePath type definition

Additional context

Prior to this update, extensions were being added to directory index specifiers thus resulting in errors like this one:
