Enhance parser to understand TS's `declare module`

I was asked to open this issue here, instead of in [eslint-import-resolver-typescript](https://github.com/import-js/eslint-import-resolver-typescript/issues/448)

After upgrading from `eslint-import-resolver-typescript` version 3.8.3 to 4.3.4 and I am getting errors that there are pretty much no exports availaboe from [@uidotdev/usehooks](https://github.com/uidotdev/usehooks).

The breaking change seems to be with version 3.9.0, when there was a migration between resolvers.

Here is a repository that shows the issue: https://github.com/Brandon-Ritchie/eslint-import-reproduction

Start by running the linked eslint-import-reproduction repository against eslint-import-resolver-typescript 3.8.3 and 4.3.4, focusing on the change introduced in 3.9.0. Trace how the parser handles TypeScript's `declare module` and verify that @uidotdev/usehooks exports are recognized correctly after the fix.
