v0.3.0

Added

• Introspection API via the new .HasMember() method, available on applicable structure builders
• More null arguments sanitizing in public methods and consecutively more ArgumentNullException and ArgumentException, which are documented in the respective methods
• Using Roslyn APIs to generate the source code via an actual AST, rather than string templates hydration

Changed

• [breaking] .ToSourceCode(bool) has been changed to .ToSourceCode(); all generated code is now formatted by default
• Refactored the internal structures from class to readonly struct
• Made better use of optionals and replaced some nullables
• Enums no longer have a trailing comma

Fixed

• Fixes the issue described in PR#13 - source code template strings were breaking when hydration keywords were used by consumer code
