Clean up wallet syncing code (#2108)

* const fn

* sync options

* move instead of clone

* combinators

* rm unnecessary cloning 1

* rm unnecessary cloning 2

* slices; impl Into<Option>

* refactor

* get rid of output_data

* nits

* clippy

* nit

* nest

* nit

* update python binding

* update nodejs binding

* update core binding

* rm output_data.py

* nit

* suggestion

Co-authored-by: Thoralf-M <[email protected]>

* rename local var

* fix tests and clippy

* ci-doc

* rm HashSet piping of foundry output ids

* rm TODO

* fix nodejs how-to

* remove todo

* undo rename

* rust: cleanup

* python: cleanup

* nodejs: cleanup

* rust: more cleanup

* ...

* ....

* .....
