This is to avoid having to reconstruct transformed distributions all the time. The direct use of bijectors also avoids going through lots of abstraction layers that could break. Instead, transformed distributions could be constructed only once when returing the VI result.

@torfjelde @Red-Portal This PR already looks good; let's try to get this PR merged in the next two weeks. |

@torfjelde @yebai As discussed, I've removed the parts directly interacting with Bijectors. I think it's ready for another review pass. (Hopeful that we're close to being done for this PR!) |

@torfjelde a reminder on this. |

Having a proper look now:) |

I've added a few more comments, most of which should be quick accepts.
There's one one argument ordering of reparam_with_entropy that is potentially "discussable", but it should be a simple change if you accept it.
So. I think the time as come 👀
I am ready accept the PR 🙏
But this is really great work @Red-Portal 👏 And thank you so much for your persistence and just continuously chipping away ❤️ It must have been a pain, but I do think the PR is a much better state now than when we started, so it's been worth it:)
