feat: Add support for Mapped Types

[roboz0r]

declare const NODES: readonly ["a", "button"];
type Primitives = {
    [E in (typeof NODES)[number]]: boolean;
};

transforms to

[<AllowNullLiteral>]
[<Interface>]
type Primitives =
    abstract member a: bool with get, set
    abstract member button: bool with get, set

Summary

• Adds new GlueType.MappedType Add support for MappedType #119
• Adds ObjectType to IndexedAccessType
• Adds corresponding transform functions
• Introduces FsToolkit.ErrorHandling to improve readability Look into use FsToolkit.ErrorHandling to make the code easier to read #123
