Code cleanup, docs, TS types (#278)

* Fix test TS types

Prefer relative imports over @imports

* Add tuple names SerialisedLLinkArray

* nit

* [Refactor] LGraphCanvas.computeConnectionPoint

* [Refactor] Add LGraphCanvas.#dirty()

* Remove string LLink IDs

No downstream support for strings at present.

* nit - Rename

* nit

* nit

* nit - Remove unused code

* nit - Doc

* nit

* nit - Remove redundant code

* Remove unused: LGraphCanvas.isOverNodeBox

* Optimise - remove 2d context save/restore

* [Refactor] Move node collapsed check to class

* Add minor code change to support stricter types

* Revert accidental deletion in 0f2d04d
