Typescript LGraphCanvas (#202)

* Format only

* Revert accidental change

* Fix redundant falsy check - uninit. var

* nit - Refactor const/let

* nit - Refactor const/let (manual)

* nit - Redeclared params

* Add TS types & minor refactor only

* Refactor - Clean up / reformat

- Add strings.ts helper functions
- Remove unused vars & local function params
- Simplifies code
- Rename vars for clarity
- Add TODOs and other comments
- Add ts-expect-error

* Redirect draw.ts enums to global file (temp.)

Should be revisited after TS merge complete
Corrects import of types from draw.ts into interfaces

* Add measure.ts - move util funcs from Global

* Add all imports required for TS conversion

* Refactor - TS narrowing

* nit - TS types & minor refactor

* Add missing types from recent PRs

Removes duplicate declarations
Fixes some type mismatches

* nit - Refactor recent PRs

* Revert incorrect decls backported

* Remove unused params

* Add TS types only

* Fix minor TS type coercion issues

Also removes redundant code

* nit - Refactor

* Remove @ts-nocheck

* Fix refactor regression - drag link to output

Issue was the result of fixing var declared outside of closure

* Restore original logic
