Initial release v0.1.0 (#11)

This gem works with Sorbet's static type checker and type definitions. It'll return a statically-typed object or throws `T::CoercionError` if the coercion fails.

It provides a simple and generic way of coercing types in a sorbet-typed project. It is particularly useful when we're dealing with external API responses and controller parameters.

```ruby
converted = T::Coerce[<Type>].new.from(<value>)

T.reveal_type(converted) # <Type>
```

The supported types include
- Simple Types (Integer, String, etc.)
- Custom Types: If the values can be coerced by `.new`
- `T.nilable(<supported type>)`
- `T::Array[<supported type>]`
- Subclasses of `T::Struct`

We don't support
- `T::Hash` (currently)
- `T.any(<supported type>, ...)`: A union type other than `T.nilable`
