feat(@hapi/mimos): rework 4.1 version definition (DefinitelyTyped#44028)

This commit tries to re-align package definition with declared version
4.1 - before it could be moved to v5

- correct export
- namespace for types and aliases
- test added

https://github.com/hapijs/mimos/tree/v4.1.1

/cc @luiso1979

Thanks!

Fixes DefinitelyTyped#43987
