Kotlin To-Do's

[lemonmojo]

• [x] Rename the class that encapsulates the JNA bindings to something like "CAPI" or "JNAAPI"
• [x] The native library name is currently hardcoded. I guess it should be derived from the target assembly name or from a build config value once automatic builds are supported. Oh it can't be derived from the target assembly because that's not the same as the native one so it must come from a config value. (added in https://github.com/royalapplications/beyondnet/commit/ec19a5c38fa5971e09d6b9a6b609ba321b9b0469)
• [ ] Ensure unsigned integers are handled correctly (see https://www.mkammerer.de/blog/jna-and-unsigned-integers/). NOTE: Tests suggest that everything works properly but I'm still not quite sure if it's correct.
• [x] Fix Nullability of method parameters (potentially also other cases)
• [x] Interfaces (added in https://github.com/royalapplications/beyondnet/commit/bac7635c0e3182258710793472d1fd1d02432782)
• [ ] Casting/Type Checking (added in https://github.com/royalapplications/beyondnet/commit/facd6874b376bee2b77d44c4c7113a470f2513b6) ToDo: The generic castAs/To functions use Java reflection which obviously is less than ideal. Maybe there's a better way to solve this?
• [x] Implement equality operators for DNObject. NOTE: As per https://kotlinlang.org/docs/operator-overloading.html#equality-and-inequality-operators identity checks (ie. === and !===) cannot be overridden so we can only implement/override equals (==, !=).
• [x] By ref arguments (added in https://github.com/royalapplications/beyondnet/commit/c1acdae14505a5a5c148394a8cf51e1d63a0a976)
• [x] Out parameter placeholders (like in Swift) (see Memory to allocate a temporary pointer; it's automatically freed when GCed)
• [x] Boxing/Unboxing
• [x] Extension methods (added in https://github.com/royalapplications/beyondnet/commit/3666e8af0dd5e83e11bbc03821de9fb70d50e39c)
• [x] Arrays (added in https://github.com/royalapplications/beyondnet/commit/66ecb3887ea9073d3f7c8de5de6644249e04d301)
• [ ] Multidimensional Arrays
• [x] Add date conversion extension methods (added in https://github.com/royalapplications/beyondnet/commit/a3183731f7f6f3aab9637228e40555ea361928db)
• [x] Add Guid/UUID conversion extension methods (added in https://github.com/royalapplications/beyondnet/commit/54ec1c10f0ba75c187e00eeb5048b8d6f82f84f5)
• [x] byte[]/sbyte[] -> UByteArray/ByteArray conversions (added in https://github.com/royalapplications/beyondnet/commit/6929f5aa1ae3ffce88235dae2b90ebd2c269ff2f)
• [x] UByteArray/ByteArray -> byte[]/sbyte[] conversions (added in https://github.com/royalapplications/beyondnet/commit/90ffb4408aea7f201c0c34a35c8c927ab112d8c2)
• [ ] ReadOnlySpanOfByte
• [ ] Delegates/Events
• [ ] Typealiases to restore namespace hierarchy
• [ ] Generate properties and fields as Kotlin properties instead of methods suffixed with _get/_set
• [ ] Automatic build support
