v0.5.1: Use swc in resolve_with_extension (#57)

Added resolver to get resolved files with extension in order to avoid
files with multiple `.` on it's name to resolve a different extension:

Currently imports such as
`graphql/__generated__/getBuildingQuery.interface` resolves with
extension `interface` instead of `ts`.

`resolve_with_extension` uses `swc` import resolver to retrieve resolved
files with the full extension of the file even when it has `.` in the
name.

v0.5.0: Added metadata struct for exported items (#53)

Added struct to attach metadata of export statements:
- `ExportedItem` enum becomes `ExportType`
- `ExportedItemMetadata` contains the `ExportType` and `allow_unused`
flag, calculated during AST walk.
- `ExportedItemMetadata` contains the span (bytepos of the export
statement)
- `ExportedItem` attaches the file path as `PathBuf` type.

`ExportedItem` attaches the file `PathBuf` right after ast walk since
the process that finds unused exports and files removes extension from
files.
TODO: add config option `supress_existing_unused` feature that adds `//
@ALLOW-UNUSED-EXPORT` comment on found unused items and
`supress_existing_unused_message` to add information to those comments.
