[x] Update README after also merging vignette PR to use mnist + flattening + link to articles on pkgdown
[x] simple vignette on pipeop torch + rename the existing one
[x] write tests for new features
[x] Test that PipeOpTorchModel properly clones the loss, callbacks and optimizer field
[x] Check how the output names are generated, when outputs of non-terminal nodes are used
in "outputmap" ("output_output.")
Important changes:
PipeOpTorchModel is now a PipeOpTorchLearner, so things like $base_learner() and set_validate work.
Added the support to make callbacks, loss and optimizer parameters instead of construction arguments to enable PipeOpTorchModel inheriting from PipeOpLearner
