use ttypescript instead of patching ts-node

[ZPiDER666]

deepkit does some magic in patching ts-node, so it executes the deepkit transformer.
with ts-node updates these patches need to be reapplied and they may even break with some ts-node changes.
i think i managed to do a setup with ttypescript that still executes the ttypescript transformer and it feels cleaner to me, but it currently does not fully work (debugger issue, see issue 445). making this a user choice may not be feasible (unless there would be a separate deepkit package to include with this "flavor").

i would prefer, if ttypescript would be used, as i want to use transformers for other things as well in my projects.

what are your thoughts on this?

Deepkit doesn't patch ts-node.
It patches typescript by adding very little code to an internal function called getTransformers, which doesn't interfere with ttypescript or ts-node.

You can see what it patches in this file

ttypescript is supported #401 (comment)
note however that ttypescript seems to be unmaintained and doesn't support TS 5+. funny enough, a ttypescript replacement called ts-patch works like what we do currently with patching typescript itself. We had never problems with our mechanism, even with the big TS v5 change (ts-patch didnt work for v5 nonara/ts-patch#93)
